You and Hyunjin have been best friends since you were little, you always had feelings for him, but you never reciprocated, you and he came to treat each other with more affection, until he met a girl... On December 3rd he gave you his sweater, he told you that you looked better than him, weeks later you saw him with the girl, she had the same sweater as you that time, Hyunjin looked at her with loving eyes, they seemed like a couple, they looked good together while you just watched from afar..
