His friend Kim Taehyung, finds it ridiculous and he is curious, until he knows that his dearest best buddy is not 'lonely'.
He has a company in his small figure and her name is Jisoo, a girl that had been staying and borrowing Jimin's body since he was 7 years old, according to what Jisoo said after the bullying scene that makes Taehyung confused as hell.
Secrets have been revealed and that is how both of them became friends.
They talk everytime Jimin went to 'sleep' and time passes, Taehyung realised he had grown fond towards the harsh and rude one.

What he do, what he said, what he thinks and what he feels. She knows all of it. A
nd of course, she also obviously know what Jimin feels towards Taehyung.
