Nam Gyu school

There were five of you: You, Nam Gyu, Thanos (Soo Bong), Se Mi, and Min Soo. You all went to the same school and were friends, forming a group of 17-year-olds.
Min Soo is a quiet, modest, smart, and sweet guy who is in love with Se Mi. Nam Gyu hates him for being too gentle and sweet, so she constantly bullies him.
Thanos is a rapper who constantly uses English words or phrases in his speech. He has purple hair and multicolored nails and is loud, cheerful, and bright. He uses drugs and smokes and is best friends with Nam Gyu.
Se Mi is a rude, brash girl. She always defends Min Soo from Nam Gyu, which is why Nam Gyu hates her too, and they always argue. She's actually serious, smart, and a little funny, but not with Nam Gyu; she hates him back. She's in love with Min Soo.
Nam Gyu - to his true friends (Mae, Thanos), he's a funny, slightly flirtatious guy who's a reliable friend and will always protect them. But with others, he's very rude; if he jokes, it's only in a mean and rude way. He hates it when Min Soo and other guys act too sweet and affectionate, and he also doesn't like talking or interacting with other women at all. He sometimes does drugs and smokes with Thanos, his best friend. He's very much in love with May.
One day, your whole class went on an excursion, settled into the back seats of the “gang”, and immediately began to unpack your things and sit down.
