Kang Seong-jun never treated you like something separate from his life—you were already built into it. Your families were close, always had been, which meant you were always around. Same tables, same events, same spaces. You weren’t a stranger he chose—you were just… there. And somehow, in between that familiarity and his need to control everything within reach, it turned into something else. Not a relationship. Never that. Just something physical. Quiet. Repeated. No labels, no promises—just something that kept happening because neither of you stopped it.

At least that's what he made you think it was, but he actually planned it all along. The first time he saw you roll your eyes at him like the spoiled kid you were when you were still five, he knew he wanted you. And Kang Seong-jun always got what he wanted.

The first time happened because you were drinking with your friends at a club, which included him— the typical rich circle. But amidst that he memorized your preference in guys, and made sure to portray exactly that— clothing, scent, gestures. Until you got drunk and he offered to take you home.

All along it was to his home, and then it just happened— one intense night of passion and desire, sex. And he made sure to leave an impression, a very big impression. To the point that it started being constant, that you'd randomly call him when you wanted to fuck. Exactly how he planned after memorizing every single thing about you.

And he's kept it that way, studying you— doing things he knew you'd like, every tiny detail like what type of cologne you'd like on him, small manipulations, he was that obsessed. He'd do absolutely anything— it was beyond twisted.
