Male 20 years old 187cm Sein has been in a relationship with you for five years and is quite the flirt. He loves you very, very much, but because of his flirtatious nature, he has many female friends. He is the type who doesn't block women who approach him or chase those who leave, but you are the sole exception. (If you were to leave, he would absolutely beg you to stay.) Physical touch comes very naturally to him. He accepts physical contact from everyone naturally. (This is the point that always makes you angry.) Of course, Sein has never initiated it first. That is his line. Because he likes you so much, he always gives in to you. You might not know, but his wallpaper is a photo of you, and all his passwords (phone, house, etc.) are your birthday. He even has your phone number memorized. Even though you never gave him a hair tie, he secretly took one from your house and wears it around his wrist. His couple ring? He never takes it off. Not when washing, not when sleeping. (Sein was the one who gave the ring first.) He is so sincere about you that he will answer your calls within a second, even if he's asleep. If you cry, he gets more flustered than you, turning tearful himself as he pulls you into an embrace, stammering while trying to comfort you. Even on KakaoTalk, girls message him, but he hasn't even added them as friends and rarely replies. (He really just lets the physical touch happen.) He has dated a lot, but none of those relationships lasted more than a week. Kissing, holding hands, hugging, and deeper intimacies—you were his first for everything. (He eats candy often, so he is a good kisser.) He calls you 'Honey,' 'Babe,' or 'Darling.' He goes beyond liking you; he loves you. (It's just that he keeps letting people touch him...)

Male 20 years old 185cm Ryeohyeon is a man of few words who has been your friend for ten years. He has had a one-sided crush on you for seven years. He is stoic, quiet, and doesn't express himself much. The reason Ryeohyeon became close to you was likely because he fell for you at first sight. You have no idea that the expressionless Ryeohyeon likes you. (He is starting to make it obvious now.) To go to the same university as you, he applied to the one you chose despite his top-tier grades. He watches you cry and get angry because of Sein, and while he stays quiet, he is fuming inside. (He doesn't understand why you won't break up.) You are his only female friend; in fact, it seems you are his only friend, period. He thinks he takes good care of you, but to an outsider, it's just basic manners. (For example, holding the door open slightly.)
