I Was Heartbroken After Discovering My Girlfriend’s Infidelity, but Suddenly I Became Popular With Girls - 7

Chapter 7: Storming the Scene of the Affair — A Dramatic Showdown

ーーーーーーーーーーーーーーーーーーーー

“Yuna, I get it. Once you turn 25, we can date and get married openly, right?”

“Right, that’s it. At that time, I can finally become Yuna Kanzaki instead of Yuna Aida. So for now, keep it a secret from everyone that I’m your girlfriend. If it leaks out, Ryousuke-san might be sued for damages, and of course, if that happens, I think they’ll cut ties with me.”

It feels like I’m having an affair.

“I see. So, we can’t get engaged or married for three years.”

“We’re both still young, so let’s bear with it for about three more years.”

“I see… Well then, for the next three years, Yuna, you’re my sex friend. Since we can’t date or go public with our relationship. We can only meet in this room or my room, so there’s nothing to do but have sex, right?”

“Hmm, I guess it turns out that way. If you’ll have sex with me, maybe that’s fine. But, a ‘sex friend,’ huh…”

“A friend who has sex. Since I can’t openly tell anyone that Yuna is my girlfriend.”

“But make me your official girlfriend once I turn 25, okay?”

“Of course. But until then, I want a temporary girlfriend. I want to go out to eat and drink with a woman every once in a while.”

Perhaps at that moment, I was confused from just hearing Yuna’s story. I only said it on the off chance it might work, but to my surprise, Yuna gave me her permission.

“Well, if it’s just that much, it’s fine. It’s a temporary girlfriend you aren’t serious about, right? Besides, you’re breaking up with Riona-san, aren’t you?”

“Naturally. I absolutely promise you that.”

Yuna gave me a bright smile.

“Then it’s okay. Well then, from now on, please look after me as your sex friend until I turn 25. On days when you don’t have errands, make sure to hold me properly.”

“Got it. I want to hold Yuna every day too. By the way, Yuna, how much did you get for the settlement?”

“A total of fifty million yen. This includes hush money too. If word ever got out that he took in a 15-year-old girl and made her a sex slave, that man would be finished. That’s why I was paid to stay absolutely silent. The amount includes that hush money. But I told you because I don’t want to lie to Ryousuke-san. So please don’t tell anyone, Ryousuke-san. I told you because I trust you. I’ve received half now, twenty-five million. I’ll get the remaining half in three years.”

“Of course, even if my mouth were torn open, I wouldn’t tell anyone Yuna’s secret for the sake of Yuna’s honor as well. Let’s take this matter to our graves. But it would be bad if Aida-san found out about our relationship. He might suspect Yuna told me everything and bury us in the shadows.”

“Yes, so we have to be careful. You take care too, Ryousuke-san. It seems the statute of limitations kicks in when I turn 26, so he’ll feel safe cutting ties with me then.”

Thus, I became Yuna’s sex friend.

Well, I’m in love with her and intend to have her become my girlfriend officially in three years, but I’ll try to correct Yuna’s sexual fetishes as much as possible during those three years. Anal sex aside, I’d like her to give up on things like public exposure and enemas. But can an exposure habit really be corrected in just three years? I have no way of knowing if Yuna goes out shopping without underwear on her own. I wonder what I should do.

I ended up having every meal at Yuna’s place.

“From now on we’ll be eating together so I won’t be lonely, and the food tastes better too.”

She was delighted, and I felt the same way. Yuna apparently did all the housework until she was 14, so her cooking was quite good. Because of that, I decided to give Yuna 200,000 yen every month for food expenses.

“If I get this much, it’ll cover all my living expenses. When it comes to buying things with my own money, my old habits of being poor come out. I can’t buy expensive things. I already have lots of brand-name clothes and shoes I’ve used until now, so I don’t think I’ll need to buy any for a while.”

She was happy that she could save all the money transferred from Aida-san. When Yuna moved to this apartment, she apparently brought all the clothes and accessories she had received. Not only did Aida-san say nothing, he even told her to take the small items she had been using.

◇ ◆ ◇ ◆ ◇ ◆

It was 10:00 AM on Monday when I arrived at the private investigation agency recommended by my administrative scrivener friend. My day trading today would have to wait until the afternoon session. I explained the situation, and it was decided that two people would stake out Riona’s apartment starting tonight.

“So, we watch from 7:00 PM to 10:00 PM, and if a man enters the room, we just contact you, Tawara-san?”

“Yes, that’s all that’s necessary.”

“The stakeout will likely last four days at the most. The cost for two people is 50,000 yen per day. Is that acceptable?”

“Yes, that’s fine.”

The meeting with the agency ended like that. After that, I just needed to change the PIN for my apartment. I immediately changed the PIN at the manager’s office. With this, Riona couldn’t even enter the entrance of my apartment building. The moment came sooner than I expected. That night, shortly after 8:00 PM, I received a call from the person in charge at the agency.

“Tawara-san, a young man just entered the room. I didn’t have instructions, but I took a photo just in case. We’ll withdraw now. The mission is accomplished.”

(Now then, time to go.)

It was about a 15-minute walk from my apartment to Riona’s. I headed to Riona’s apartment with the spare key I had prepared and a bottle of Bordeaux wine in hand.

“Have a good trip. Good luck!”

Yuna, wearing only an apron, cheered me on with a smile. 

(All right, I felt motivated to do my best.)

However, a bit of a problem occurred. When I arrived at Riona’s apartment, I bumped into Riona’s younger sister, Nanami-chan. She was as beautiful as ever. No, she had become even cuter than before. Five months had passed since she moved from the countryside to Tokyo. She had become quite stylish and seemed to be wearing a little makeup.

“Ah, good evening, Ryousuke-san. It’s been a long time. Um, did you come to see my sister?”

Right, Riona’s room was on the second floor of the apartment, but Nanami-chan lived on the first floor.

“Good evening, Nanami-chan. That’s right. Err, are you on your way back from work?”

“Yes, I am. But this is rare. I heard from my sister that Ryousuke-san doesn’t come to her room.”

“Well, I did something bad to Riona the other day. I came to make up for it today. Look at this.”

“Wow, is that wine? It looks expensive.”

“Yeah, I thought I’d give Riona a surprise.”

“…Big sis… how nice… Um, can I go with you? There’s no one in my room and it’s a bit lonely. It’s been a while since I’ve seen you, Ryousuke-san.”

This turned into a bad situation. It was about to become a mess, but I couldn’t think of a reason to refuse.

“Uh… what should I do…”

Despite my troubled expression, Nanami-chan pushed forward.

“Isn’t it fine? It’s a surprise, right? It sounds fun, and I want to talk to Ryousuke-san.”

Ah, there was no reason to refuse. I just hoped Nanami-chan wouldn’t be traumatized by the scene that was about to unfold.

“Then, shall we go? Be quiet, okay? Let’s surprise Riona.”

“Yes! Okay, let’s go.”

Nanami-chan and I quietly climbed the stairs. Riona’s room was a 1DK, and opening the front door led to the bathroom, toilet, and a kitchen-dining area. Beyond that was an eight-tatami room with a bed and a table. The front door was locked. I opened it with the spare key and we entered quietly. Nanami-chan, knowing nothing, was smiling. My heart was pounding. Then, I opened the door to the back room.

Sure enough, there on the bed were a naked man and Riona. Furthermore, they were right in the middle of having sex in the doggy-style position.

“Kyaaaaaaa!”

Nanami-chan let out a scream. To Nanami-chan, it must have looked like Riona was being attacked by a strange man. She suddenly ran toward the entrance and went outside. I had intended to take a photo, but I was startled by Nanami-chan’s scream and instinctively froze.

“Who the hell are you people, barging in like this!”

The moment the man yelled, Riona stood up. I didn’t miss the squelching sound as the penis pulled out of her vagina.

“Ryo-kun, why…”

But at that moment, I was distracted by Nanami-chan’s voice.

“Hello, police? There’s a strange man in my sister’s room and she’s being attacked. Please help. Eh, the location? The location is…”

(Crap, this is turning into something terrible. I have to stop Nanami-chan. )

However, Riona didn’t notice and was clinging to my leg while still naked, making excuses.

“Ryo-kun, you’re wrong, this isn’t what it looks like. Please, listen to me.”

(This isn’t the time for that, the police are being called! )

I tried to head to the entrance to stop Nanami-chan, but Riona wouldn’t let go of my leg.

“You, who the hell are you? Why did you come in here?”

The man yelled at me while putting on his underwear, so I told him.

“I’m the boyfriend of the woman you were just raping.”

“Ha? Bo-boyfriend? It wasn’t rape, we’re dating!”

Riona started wailing, crying out, “You’re wrong, waaaah!” I never imagined they’d be naked and having sex within 30 minutes of entering the room. I had hoped to break up with Riona quietly and amicably if possible, so why did it turn out like this?

“Mo-more importantly, Nanami-chan called the police. I have to stop her.”

“Ehh, the police? Why? Who was that woman?”

“Riona, hurry up and get dressed. The police are coming. Hey, man, you too.”

Nanami-chan came back in then.

“Ryousuke-san, I called the police. They said there’s a patrol car nearby. They’ll be here soon.”

I could hear the sound of sirens approaching.

Things were a mess after that. Because the record of the 110 call remained at the police station, the responding officers said they had to write a report, and in the end, statements were taken. It was truly the worst. Riona was naked, the man was half-naked, Riona was in a state of semi-frenzy, and the man was confused and snapping at the officers. A crowd of onlookers gathered, and Nanami-chan kept apologizing, saying, “I’m sorry, it was a misunderstanding!” Riona probably wouldn’t be able to live here anymore.

However, through the police report, the man’s identity and the details of the affair became clear.

“We understand this isn’t a criminal case. Since this is a civil matter from here on, we’ll be withdrawing. But you’ve certainly had a rough time,” the older officer said sympathetically.

The man was named Arai Toshimitsu. He was a new employee at N Securities and Riona’s colleague. Apparently, they hit it off at a mixer two weeks ago, and Riona had invited him to her room. Riona claimed she only went to that mixer to make up the numbers, but I couldn’t believe her. Nanami-chan was suspicious too. The man was angry until the end. It was likely because he was interrupted mid-sex. I had an IC recorder ready. Then, I started recording.

“I don’t know who you are, but I’m Kanou-san’s boyfriend. You aren’t wanted here.”

“Arai-kun, you’re the one who isn’t wanted. My only boyfriend is Ryo-kun. Don’t get the wrong idea. To me, someone like you is no better than trash compared to Ryo-kun.”

“Eh, Kanou-san, you said you liked me best!”

“Liar! I never said that. Believe me, Ryo-kun!”

Nanami-chan and I were completely disillusioned.

“Hey, was it Arai-kun? Didn’t Riona tell you she had a boyfriend?”

“She didn’t. She told me she wanted a boyfriend. So you were dumped by Kanou-san a long time ago. Don’t you get that?”

“Big sister, you’re the worst. Truly the absolute worst.”

“No! I didn’t say that! Believe me, Ryo-kun!”

Riona was crying non-stop.

“Heh, I see. So I had already been dumped by Riona. Then it doesn’t matter anymore. I’m going home. Riona, I don’t think we’ll ever meet again, so you can throw away your toothbrush and cup at my apartment. Well, I hope you two are happy together.”

When I stood up to leave, Riona, hearing my words, clung to me in a state of semi-frenzy.

“Ryo-kun, I’m sorry, I’m sorry. I’ll never do this again, so please forgive me, I beg you.”

She was prostrating herself and sobbing loudly. Seeing that, the Arai guy seemed surprised. And it seemed he finally understood that he was just a side piece.

“Um, I’ll be taking my leave now.”

He tried to run away.

“Wait a minute. Do you really, truly love Riona? If so, date Riona seriously from now on. You can’t just hit it and quit it.”

“No way and saying ‘hit it and quit it’ is offensive. I only came because Kanou-san invited me to her room. I have no intention of dating her seriously anymore. No matter if she’s the most popular beauty among our colleagues, I have no desire to date someone who calls me trash.”

“I see, got it. Then you can go home.”

The Arai guy left looking sullen. But it seemed he had sex with Riona nearly ten times. I had no interest in Riona anymore and I was utterly appalled, but I felt like I couldn’t let this go. Maybe I’d go to N Securities tomorrow, close my account, and withdraw all my assets. Of course, I’d tell them the reason for closing it. 

(Now, I wonder what the person in charge will say. I can’t wait.)
