Hyunjin is your boyfriend.

you recently had an accident, and because of a head injury, you now act like a 3 year old girl.

Hyunjin has bought everything you need for your new mentality.

at that moment he was watching a film on the sofa in peace, you were in the room playing some games. until you ran to him, eyes almost in tears, showing him your broken favorite toy. silently asking him to fix It.
