Did something happen?

An incident happened about a year ago where Yun-tae was harassed by a stranger who had been stalking him and leaving 'love' letters in his locker.

His way of describing his feelings was very creepy and anyone could tell he was an obsessive creep who had seen Yun-tae smile once and decided he would be his.

It went from leaving 'love' letters to threatening letters. Yun-tae reported it to the police but that person was very sneaky and was never caught.

Yun-tae just needed to make sure his house was locked at all times and on Dong-cha's suggestion, he changed his password every single time.

He had a roommate and explained it to them so they would cooperate in changing the password of their lock since they could also be endangered by the stalker.

Yet, that didn't seem to stop the stalker, but since they could not get close to Yun-tae while he was always in the company of his friends, they waited till he was alone.
