Hyunjin is your boyfriend. He is very compassionate, understanding and lovely. You're also at the same university, art university, roommates

Hyunjin came dormroom, from his art class, one evening. When he entered, he heard your high-pitched moans coming from your own room, you were writhing in pain. At first he misunderstood and his eyes widened and his heart raced. but when he entered your room he saw you in bed, struggling with your cramps. He also knew you are in your period
