I Was Heartbroken After Discovering My Girlfriend’s Infidelity, but Suddenly I Became Popular With Girls - 1

Chapter 1: The Wife Next Door

ーーーーーーーーーーーーーーーーーーーー

The first time I met the Aida couple was the evening of three days ago. It was the Aida couple who had moved into the unit next to mine. That was the first time we exchanged greetings. Holding a small box of sweets in her hand, the wife, who said, “I look forward to our future interactions,” was a beauty who left a fragile impression. The husband gave off a cold impression. He had the air of an elite salaryman who followed an extremely rigid profession.

Since I hadn’t asked their ages, I didn’t know for sure, but the husband seemed to be somewhere between forty and fifty years old. However, no matter how I looked at her, the wife appeared to be in her early twenties. I wondered if perhaps they weren’t a married couple but were in a mistress-lover relationship. But when I looked at the nameplate later, it read “Aida Souichi, Yuna,” so I supposed they really were a married couple.

(No, no. No matter how you look at it, the age gap is too wide.)

I vaguely thought they might be siblings.

(My name is Ryousuke Tawara, twenty-four years old.)

Three years ago, when I was still a university student, my parents and my older brother’s family were returning from a hot spring trip in the mountains when a sightseeing bus rear-ended them. The car my brother was driving went over the guardrail and plunged down a cliff, and everyone died in the accident. I became truly alone in the world, save for a few relatives I occasionally associated with, but through the inheritance, insurance money, and settlement for the accident, I came into a sum of money in the high nine-figure range. I deposited the majority of that money with a securities firm and a trust bank for asset management. And now, I worked as a day trader using about one hundred million yen.

I moved into this newly built tower mansion two months ago. I bought it because I liked the fact that it was a corner unit. The layout was a 2LDK, so I thought it was intended for a single person or perhaps a newlywed couple. And so, it was three days ago that the Aida couple moved into the unit next door. Since I had received the box of sweets recently, I decided to buy some cakes from a nearby pâtissier and deliver them as a return gift.

“Excuse me, it’s Tawara from next door.”

“Coming!” 

I heard a cute voice that sounded like a ringing bell, and the wife opened the door for me. Seeing her again, she really was an incredible beauty. She was a Japanese-style beauty with long black hair and an outstanding figure that was curved in all the right places. This was the first time I had seen such a perfect beauty. There had been no one like her even at my university. She was a woman with a fragile yet sexy aura, closely resembling the adult video actress Furu… Iori-san.

“Um, this is a return gift for the other day. Thank you very much.”

“Oh my, you didn’t have to get me a return gift. Well, thank you very much for this.

Please, please, do come in.”

I never imagined I would be invited into a newlywed’s home, but following her suggestion, I said, “Well then, excuse me,” and entered the room. The room was filled with chic furniture, calm green curtains, and an expensive-looking white leather sofa. However, for a place where a married couple lived, it felt as though it lacked the scent of daily life.

“My, what delicious-looking cakes. They’re from that pâtissier over there, aren’t they?”

While she brewed some black tea, I found myself inadvertently captivated by her beautiful appearance and gestures.

“Today is a weekday, but are you off from work?”

“No, I work from home as an investor.”

“Oh, so you do things like stock trading or FX?”

“Yes. Well, I leave the majority of my assets to a securities firm’s fund or investment trusts, but I do day trading myself as well.”

“I see. In that case, could you teach me about asset management sometime? I want to increase the alimony I received from my husband, even if only by a little.”

“Eh? Alimony from your husband?”

What did that mean? There were definitely two names on the nameplate. Alimony for what?

“Yes, normally that would be a surprise, wouldn’t it? Actually, due to various circumstances, we married on the premise of a divorce. To be precise, we plan to officially divorce in three years, but I have already received this place and a lump sum of money. We are already living separately, and my husband never comes here, but he transfers monthly living expenses to me until the divorce.”

I wanted to ask about those “various circumstances” in detail, but I gave up, deciding now was not the time. However, I thought it would be strange if there wasn’t a significant reason for someone to easily let go of such a beautiful woman.

“I see, I understand. I’m against investing your living expenses, but if it’s not that, I’ll help you.”

“Really? Thank you so much. I’m a complete beginner, but I look forward to your guidance.”

It was a stroke of incredible luck, like a boat arriving just when I needed to cross. I was happy just to have established a connection where I could openly associate with the super beauty in front of me from now on. In time, we might even develop a physical relationship.

(No, that’s probably impossible, though.)

“Well then, Mrs. Aida.”

“Um, being called ‘Mrs.’ is… a bit… Let’s see. Please call me Yuna from now on. Since I’m not really a ‘Mrs.’ anymore.”

(Is that how it is? She isn’t divorced yet, is she? Well, whatever.)

“……Yes. Then, is… Yuna-san… alright?”

“Yes! Please call me that. By the way, what should I call you, Tawara-san? What is your first name?”

“Eh? Yes… it’s Ryousuke.”

“Then I’ll call you Ryousuke-san.”

It was surprising that we had become close enough to call each other “Yuna-san” and “Ryousuke-san” in such a short time after meeting. Under normal circumstances, such a thing would be impossible.

“Um, Yuna-san.”

“Yes! What is it?”

Yuna-san looked very happy.

“Well, for asset management, you would normally use a securities firm or a trust bank’s fund, but for individual stock investment, will you do it yourself? Or will you stick only to funds?”

“Let’s see. I’d like to decide that based on your opinion, Ryousuke-san.”

“Well, you see, to perform individual stock trading, you need to study for at least one to two years. You have to start with the most basic studies. If you do it haphazardly, you will definitely get burned. To choose brands, you need sufficient knowledge and research.”

“I understand. I look forward to your guidance and encouragement. Ah, this is becoming fun.”

Looking at Yuna-san’s captivating smile, I realized I was becoming attracted to her. I thought that if it was for her sake, I didn’t mind if a certain amount of my time was taken up. Then, we exchanged contact information. We were contacting mainly on LINE.

After that, I gave Yuna-san some beginner books on investment that I had used for my own studies.

“Please make notes of anything you don’t understand. I’ll explain it in detail later.”

Yuna-san studied enthusiastically, repeating that process many times, but it took four weeks for her to completely understand the first book. The study sessions with Yuna-san were a blissful time, and for me, it was like killing two birds with one stone because I could return to my roots. The study sessions were held every day at Yuna-san’s house for about three hours starting at 4:00 PM, after the afternoon market closed. I could not stop myself from becoming more and more attracted to Yuna-san.

However, Yuna-san didn’t talk much about herself, and I was too afraid of breaking our relationship to ask. She would probably tell me once we became more unreserved. But I had a girlfriend, and Yuna-san had a husband. Besides, at that time, I thought it was impossible for something to happen between me and a woman as high-class as Yuna-san.
