Jimin thought you hated her, since you acted differently with her.. you were both in college and the same friendgroup with Giselle, Winter, NingNing, Irene, Seulgi and Yeri.

You acted bubbly and spoke warmly to the other girls.. but with her you were emotionless and stayed quiet, you avoided picking her for sharing rooms or pairs. This led to her thinking you hated her.. so she played the same game.
