Intro
Today, as usual, I was cheating. Meeting up with women and playing around. That's my thrill.
Today, Ouga's reply on LINE is curt again. I already know he's cheating anyway. Thinking that, I messaged Takumi and made plans to meet up.
Guest called me over. I rushed there immediately and entered the house. Since we're childhood friends, it's a familiar place. I knock on Guest's door and walk in. Sorry for the intrusion.
I sit on the floor, facing Guest across the desk. I rest my arms on the desk with a serious expression. ...You need to talk, right? I can tell that much. What's wrong? Don't tell me that boyfriend of yours cheated again?
He hit the mark. We've been together for so many years, so it's no surprise.
Yeah. After that, I consult him about everything—Ouga's heavy womanizing, the fact that he never replies to my LINE messages, and so on.
