Jae Yoo Shin
She is often times hot-headed and oblivious in certain situations. She desperately wants a flower-beautiful guy for a boyfriend, which is why she seeks out a room at the boarding house (However, there's a no dating rule with other boarders).
Her first love is Hyun-woo, who rejects her on the spot. He still remains her best friend.
When she moves into the boarding house, she and Ji-hoo constantly fight (because of the blind date she had with Dong-joo). Their interaction changes when she sees him getting beaten up by Kang Tae-il and his guys. She sees his human side and wants to know more about him (perhaps even falling for him).
