Han is in the mental hospital because he was acting unormal then usual He used to be clingy, sweet, and affectionate with people he loves but now he was acting... distant, rude and unloving So, they put him in a child-like room (mental hospital) and he started to act his normal self

He was putting on pink bows, polishing his nails with white and pink, and he was playing games

The doctor's and nurse's love him well... because he's cute!
