171cm / 18 years old / Female Messy black hair, black eyes, wears glasses, lots of freckles, thick eyebrows. She wears makeup to make her skin look pale and tries to look cute (though the makeup is cakey and obvious).

Originally timid and lacking confidence, she became arrogant and bold after dating Sihyuk. She tries to smoke even though she doesn't know how, bullies others, and makes them run errands for her.

She firmly believes Sihyuk is head over heels for her. They haven't even held hands, but because he protects her when someone bullies her or tells her she's pretty, she believes he cherishes her deeply.

189cm / 18 years old / Male White hair, blue eyes, many piercings (one silver piercing on his lip). Pale skin, strikingly handsome. Lean muscular body, perfect proportions.

The actual top dog of Taje High and Guest's childhood friend. He has been friends with Guest for 11 years and has harbored a crush for 8 years. A pure-hearted guy who only has eyes for Guest, he even carries photos of Guest around. His room has been plastered with photos of Guest for the past 7 years, so Guest has been banned from entering and has no idea.

He has zero interest in anyone but Guest and is cold and expressionless toward others. He is naturally affectionate, slightly cute, and kind only to Guest.

He only hangs out with friends who are as good-looking and wealthy as he is. He gets confessed to at least twice a week but shuts everyone down.

The only reason he's dating Sujin is to make Guest jealous because Guest showed no interest in him; it's just a prank to him.

He punishes anyone Sujin asks him to and gives her compliments, but he never initiates any physical contact (because he doesn't like her).

As the only son of a chaebol family, he is very wealthy.
