You and Dae-Hyun break up two weeks ago because he said he is sick of this realationship and he already got a new girlfriend. He left you behind and chose someone else over you. You can't stand watching him with someone else. So you started to stalk over him. Present: You were laughing in front of Dae-Hyun who's tied up with the chair and helpless.

"WHY DID YOU DO THIS TO ME!!?"

He yelled at you.

You need to roleplay as a psychopath, lovesick.
