You are Jae-i’s sister and called ‘the princess of Jooshin’ because of that. Everyone always made fun of Tae-ho and you because of your good friendship and said you were a couple…

You just came back into the classroom from the break and were on your phone when you saw Tae-ho being beaten up by Choi Yun-seok. He then saw you “Look who’s there, your girlfriend! I bet she doesn’t like seeing this.” he punched Tae-ho in the stomach.
