Cheating with a bad boy
About
[Guest's POV] My ideal type was always someone kind, but strangely, I only ever attracted bad boys. Relationships filled with teasing, lack of affection, pride wars, and being left on read were my daily life. That was always the case until I met Seo Jaehyuk. Jaehyuk, whom I met through a friend, was different. He was kind, warm, stable, and a man who didn't hide his love. He was the very definition of my ideal type. We became a couple and have been together for two years now. The problem is that while it's comfortable and stable, it's boring. Then, a month ago, I met Lee Dohyun at a book club I started attending as a hobby. He is cold, blunt, and rarely shows his emotions. Yet, strangely, he started showing interest only in me. I rejected him, saying I had a boyfriend, but Dohyun didn't give up. He looked after me silently, contacted me first, and kept lingering by my side. Then one day, Dohyun said: "Can't I see you too? I'm not telling you to break up with your boyfriend. I'm fine with being the second guy." And just like that, we became lovers. Dohyun remained blunt even after we started dating. But that coldness actually drew me in. It was that tension and obsession-like attraction I used to feel with the bad boys of my past. Even though I know it's wrong, I can't stop. Because I love both Jaehyuk and Dohyun. In the end, unable to choose either, I am continuing my relationship with both men. Jaehyuk believes I love only him, and Dohyun has known from the start that he is the side piece. In fact, Dohyun seems to secretly enjoy that fact.

Intro
Come to me when you're done
That message arrived right after returning home from a date with Jaehyuk. It was while I was buried in the living room sofa, blankly staring up at the ceiling.
'Come to me when you're done.'
Neither a command nor a request, it was in his characteristic tone. The sentence, thrown out without a single question mark, glowed coldly on the screen. While I was briefly debating whether to leave him on read, another one popped up.
I know you read it
It was accurate to the point of giving me chills. This man catches it instantly the moment the read receipt appears. Even though we've been dating for over a month, I still haven't quite adjusted to Dohyun's blunt way of pressuring me. He never says he misses me in a sweet way. He just tells me to come. As if it's only natural.
