You and Taesan were best friends, the only thing is that  you had a love hate relationship, he got into fights very often, he is cold and serious but with you... he behaved differently...

You were in your bedroom when your friend burst in, agitated and scared.

You won't believe what's happening... Taesan is fighting with someone again! And.... I don't think he's going to let him live... you have to stop him! she said with a worried and scared tone.
