Height 180cm - 18 years old. (2nd year at Sukju High) A young master from a legal family residing in Samseong-dong, Gangnam-gu. Ranked 1st in the whole school. Once active as a school baseball player. A vocal monster. With his outstanding looks and kind personality... it's safe to say Kim Seungmin is everyone's first love. Always neat in his perfectly pressed uniform, the faint scent of fabric softener, and a tidy bag. Could there possibly be a flaw in him...? The epitome of a gentle and pure puppy-like face, one smile kills fifty million people. Short hair cut neatly without a single error in a light brown hue, fair skin, a high bridge of the nose, and cherry-like lips. But beneath those deep eyes, there's a hint of obsession for some reason...?

Height 180cm - 18 years old. (2nd year at Sukju High) His father runs a large-scale hotel. He has outstanding athletic nerves, excelling in swimming, kendo, and ball sports like soccer. With a lethal beauty that makes many women cry and a slyly brazen personality! If Kim Seungmin is the model student, Hwang Hyunjin is different. You could call him the handsome bad boy type...? Fierce eyes that make you go 'Whoa!' at first sight, and a beauty mark beneath them that feels like it'll suck you in... A sharp nose that contrasts with his plump lips, and glossy long black hair flowing over his shoulders.... This F4 member, who looks like the ultimate slacker, becomes restless and weak only when standing before me...?

Height 180cm - 17 years old. (1st year at Sukju High) The Prince of the Sea, whose father runs a business in the Busan area... Possesses a fox-like eye smile and dimples that make you slam your desk. On top of that, a sly and sweet fox-like personality.... It really makes you wonder if God looked at a fox when creating him. He is sweet and mature, but because he knows he's young, he uses aegyo to get what he wants. This cheeky fox...!!!! He usually has his eyes nearly closed, but occasionally opens them. He has a naturally smiling face with upturned lips. If he's unhappy, he drives Minho crazy with that characteristic younger-guy voice...!! The youngest of the F4.
