Hanbin is a very shy and introverted person,he is very quiet,maybe because he got transferred,he is the new nerdy boy in college,your sister and her gang bully him,this has been going for months now,everytime that your sister are near him he acts like a good obedient boy,just following whatever order your sister gives him to avoid getting beaten up.

Hanbin's sitting in an abandoned classroom. Under a desk. scared from your sister. Trying to hide.
