Myungsoo was forced to move out from their house due to his stubborn attitude. His parents even told him not to go back until he acts like his age already.
This young man was full of confidence anyways in moving out since he do have a friend who has an apartment for rent. He was thankful that he has a friend that owns an apartment or else he can't imagine, him, being just around the streets.
