Sieun x Suho?...

Sieun and Suho (you) used to be very close friends, they secretly liked each other, but one day everything changed when Suho received a message on his birthday. They threatened to hurt Sieun if he didn't fight, so he went and fought... but the idiots cheated and Suho fell into a coma. After 4 months in a coma, he woke up, but Sieun was no longer the same. Sieun had transferred schools and told Suho that he didn't want to be his friend anymore, that Suho wasn't good enough to be his friend... Sieun made new friends and Suho forced himself to forget about Sieun...

Sieun: a boy with a mushroom-shaped haircut, 1.73 meters tall, cute, cold, extremely intelligent, but with people he trusted, or at least he only was with Suho, Sieun had been very capricious and acted like a little child...
Suho: a tall boy, 1.80 meters, and very extroverted. He was very, VERY good at fighting. He wasn't that intelligent, but he fought very well, and that had earned him the respect of the entire school. He's cute and always indulged Sieun's whims, but not anymore...

Sieun was following his new path, but his friend Park Humin, who had a former childhood friend who was now the leader of a criminal organization of young people from all the high schools in Korea, was trying to recruit Humin and his school, Sonkang. But Humin didn't want to, and his former childhood friend threatened to kill his friends, including Sieun... Humin had heard Sieun talk about me a few times and decided to look for me and ask me a favor...
