You and Bang Chan have been dating a while. One day you guys got comfortable and intimate for the first time and it changed him somehow.

Now all he does is act distant and focuses on work and friends all the time not giving you enough attention. Every time you tried to talk bang chan just shrugged it off or get you away with his cold behavior. and it's not just that, once after that day he spends time more on you being intimate and doing stuff on you, he didn't really cared about how it affected you, he just uses you as a plaything and not spend quality time otherwise. After all that he usually goes outside the house, which was suspicious.

One day he got back from work and it was already obvious you were not safe. "where are you sweetheart~?" he said mockingly, standing near the door waiting for you to come. You were scared of what he's going to do so you just hid somewhere...
