(Nanaka’s Side)

…This was the worst. Absolutely the worst.

“So you came here too, Nanaka.”

The man standing before me looked at me with a smug grin, surrounded by three girls. The women around him were undoubtedly someone else’s former girlfriends. I had long stopped feeling anger at the sight of him showing them off as if they were his possessions.

I had been wandering alone looking for a vending machine because I was thirsty. Unfortunately, I ran into him.

“Come on, Nanaka~ Don’t make such a scary face at your big brother~” 

“Eh? This girl is your little sister?” 

“She’s so cute~” 

“Right, right? My pride and joy of a sister~”

This sleazy attitude was just like always. And as always, I sighed rather than getting angry.

“Wait, if you’re here without your big brother knowing, does that mean that Nanaka came here with a boyfriend?”

“…I don’t have one. Shut up. See you.”

It was unpleasant talking to him because I hated my brother.

Just as I was ending the conversation and turning to walk in the opposite direction:

“Well, that makes sense~ The guy you like already has a girlfriend, after all~”

“What!?”

…How did he know that?

I hurriedly turned around to look at my brother, who had a disgusting grin on his face as if he knew everything.

“Well, you’re my sister after all. Let’s get along as siblings, shall we? Heh heh.”

He patted my shoulder as he passed by.

I was nothing but anxious.

If that man made contact with those two… he might ruin things again.

.

“…Found him. That guy Seo Tatsu, the manwhore…”

At noon, we were supposed to meet up again after buying food we liked at the facility’s fast food area. Being lunchtime, everyone had the same idea. Every food stall was bustling with long lines.

And there, the person I was looking for stood out in a different way.

“Tatsu-kun, say aah ♪.” 

“Mmm! Delicious. Food really does taste better when a beautiful woman feeds you~” 

“Tatsu-kun, try this too.” 

“Aah, and this one too!”

One man surrounded by five women, a harem setup. Yes, the Seo Tatsu-centered cuckold harem. The beautiful women around him were probably all someone else’s girlfriends before.

“Hey, you! What are you doing with my girlfriend?!”

A man with a mushroom haircut appeared. From his words, he was one of the five beauties’ boyfriends.

“Huh? Who are you? Does anyone know him?”

Four of them shook their heads saying they didn’t know him, but one awkwardly looked down. Tatsu immediately noticed this and smirked.

“Is this girl your girlfriend?”

“Y-yes! She’s my girlfriend! Hey, Asami! Why are you with a guy like this? This is cheating!!”

“T-that’s…”

The man was saying the right thing, but Tatsu just laughed loudly.

“W-what are you laughing at… you bastard!”

“Sorry, sorry. It’s just that you’re saying such funny things. And… cheating? Don’t make me laugh. Isn’t it your fault? I heard you’ve been busy with work lately and haven’t been having sex with your girlfriend properly.”

“T-that can’t be helped! Besides, Asami can live because of me! All she does is housework… Recently she’s been spending less time at home, so I followed her today, and sure enough, she was cheating with a young man!? Don’t mess with me!”

“Ah, there it is. The domineering husband saying ‘it’s all thanks to me’. Housework is actually quite difficult, you know? Plus dealing with neighbors and such. Also, this girl has been secretly investing in stocks without telling you, and she’s earning way more than your income. This girl is so attractive with her soft breasts and ass, and though she looks quiet, when you offer her a cock, she’ll lick it with an incredibly erotic face—she’s a top-class beauty. Keeping her next to someone like you would be a waste, so I’ve taken her. Come on, you say it too.”

Tatsu put his arm around the beauty’s shoulder. 

She calmed herself and said, “I’m going to be this man’s girlfriend♡”

The mushroom-haired man collapsed to his knees at his girlfriend’s words.

“Hahaha, in the end, it’s all about looks, technique, and dick size. If you’re going to regret it, blame yourself, ex-boyfriend ♪.”

Watching the whole thing from a distance, I was dumbfounded.

Actions that seemed to protect girls. If someone spoke so highly of you, of course you’d have a good impression of them. So with the right technique, any beautiful girlfriend would fall for him…

Unnecessarily high-spec… who did this guy think he was? 

He’s SO INFURIATING!!

Chapter 22: In This Situation, I Can’t Make His Balls Fall Off

After that, I spent all my lunch time monitoring Seo Tatsu.

I sent Isamu, our group representative, a LINE message saying “My stomach’s upset. crying face“. Based on the OK sticker he sent back, he must think this was just how I was.

“Will you hang out with me? Yay~”

As for Tatsu, he had successfully persuaded an eighth beauty to play with him. She was a mom with a child. 

Ah, I see. So he asked one of his entourage to take care of the child…

From watching Tatsu’s series of actions, I realized he didn’t forcibly seduce women through rape or threats—no such tyrannical methods of stealing girlfriends. Instead, he gave them a choice.

For example, with the mom from earlier, she was constantly watching her child and couldn’t relax. The faint dark circles under her eyes showed she was struggling with childcare.

That’s when Tatsu had swooped in. 

“My friend can watch your child. Let’s have fun together. You came here to refresh yourself, right? Even if it’s just for a short time, I’ll listen to your complaints and make sure you have a great time.” 

And that wasn’t all he was tempting her with.

He filled the void of anxiety and loneliness, causing women to change their hearts. She was the one who’d nodded in agreement. Then the cuckold sex followed and pushed things further…

I see… No, I don’t see!! This guy is a con artist, this damn manwhore! How dare he steal other people’s girlfriends!!

I could deliver a right straight to his cheek right now, but since he hadn’t actually committed rape, it would just be dismissed as “she followed him after he hit on her”.

As expected of a manwhore, scumbag, girlfriend-stealing dick, and everything else he represented. This wasn’t going to be simple…

“Shotaro-kun?”

“…? Oh, Haruka-san!”

Someone called out from behind me. Thank goodness it was Haruka… no, not good!! The target, Tatsu, was fifty meters away. If things continued like this, Haruka might catch his eye, and he’d exploit her vulnerabilities like he did with the others, creating trouble.

“Haruka-san, let’s go this way for a bit.”

“Eh, okay.”

Since taking her hand would be disrespectful to Isamu, I just led the way. I moved to a place where Tatsu couldn’t see us. He shouldn’t notice us here.

“So, what is it, Haruka-san?”

“I spotted you while walking… Is your stomach okay?”

Ah, right, that was my excuse.

“I-I’m fine, really! I’m in perfect condition now!”

“That’s good to hear. Shotaro-kun is my benefactor, so I need you to stay healthy!”

“Hm? Benefactor?”

Haruka’s expression became more formal. Happy, yet somehow sad.

Hey, I had a bad feeling about this…

“While you were keeping Nanaka-chan busy, I got to spend a lot more time with Ii-kun, and I became more confident in myself… I realized once again that I really, really love him. Then naturally I started taking action, and Ii-kun began to blush more and show me his smile more often… I’m so happy now, and it’s all thanks to you, Shotaro-kun. Thank you so much.”

“…”

Yeah, I was happy to be thanked. Especially directly from the heroine.

But… she didn’t need to raise these kinds of flags right now!!

“Shotaro-kun?”

“Ah, no… it’s nothing. I’m fine as long as you two are happy.”

“Yeah ♪. I hope Shotaro-kun finds someone nice too!”

Someone nice… if Mina were my step-sister, I might marry her right away…

In the afternoon, we decided to go to the water slides, so the four of us climbed the stairs.
