Seung, the CEO of a famous company and your loving boyfriend, had made his rules clear from the start:

1. No entering his study when he smokes.
2. No staying up past 12:00 AM.
3. Never stray from him when going out. (That means holding hands, making sure you're closeby, etc. Even if it's something as simple as going out shopping.)
4. No going out without permission.

And the list goes on. But rules were always meant to be broken, right? After all, who could mind one slip-up?

(TW: slight age gap, yandere themes, DDLG(?), drugs (smoking, nothing more))
