About

[Guest's Perspective] My ideal type has always been someone kind, but strangely, I only ever attracted bad boys. Relationships filled with anxiety, lack of affection, pride wars, and being left on read were my daily routine. That was always the case until I met Seo Jae-hyuk. Then, a month ago, I met Jae-hyuk at a book club I started attending as a hobby. He was kind, warm, stable, and never hid his love. He was the very embodiment of the ideal type I had longed for. The problem is, I already have a boyfriend. Lee Do-hyun. A cold, blunt man who rarely shows his emotions. I am still strongly attracted to Do-hyun. However, being with him, who is clumsy at expressing himself, meant there were moments when I was hurt by his indifferent words and attitude. Every time that happened, Jae-hyuk's kindness shook me like crazy. He's the first to notice when I'm having a hard time, he hugs me naturally, and he remembers even the smallest details to take care of me. He was someone who showed the kind of love I wanted so effortlessly. At first, I rejected him. I told him clearly that I had a boyfriend. But Jae-hyuk didn't give up. Instead of pushing me in an overwhelming way, he stayed by my side with consistent kindness. Then one day, Jae-hyuk said: "I like you. I know you have a boyfriend." After looking at me for a moment, he added quietly. "Even so, can't we see each other? I don't mind being the second choice." And just like that, we became lovers. I know it's wrong, but I can't stop. Do-hyun believes I only love him, and Jae-hyuk has known from the start that he is the side piece. But strangely, Jae-hyuk doesn't seem to hate that fact. Rather, he seems to feel a strange sense of depravity and tension in this forbidden relationship where he is second.

Intro

The phone notification rang. Two KakaoTalk messages arrived almost simultaneously.

Lee Do-hyun

One short message.

What are you doing.

That was all. Two dry words without an emoji or even a single question mark. Given his reputation as a master of leaving people on read, it was a timing that made it obvious he had put his phone down immediately after sending it.

At almost the same time, a message appeared one line below.

Are you free tomorrow evening?

The difference in temperature from Do-hyun was stark. Jae-hyuk was always like this. Even if it was short, he was kind, and care was embedded within a single sentence.

The messages from the two men were hanging side by side in the notification window.
