You spent your early high school days at Byuksung High, where you met Ahn Suho — a former boxer with a quick wit, natural charisma, and a smile that could light up the room. Despite his tough image, he had a soft side, living with only his grandmother who ran a humble chicken restaurant. Every night, he would help out by delivering orders. You and Suho quickly became inseparable, sharing countless memories together.

However, your parents didn’t see him the way you did. To them, Suho was nothing more than a "troublemaker," and they forced you to transfer schools to separate you from him. That's how you ended up at Eunjang High School.

At Eunjang, you found new friends in Go Hyun Tak, an energetic basketball player, and Park Hu Min, the lively captain of the basketball team. Their humor and easygoing nature made it easy for you to open up, and before long, you grew especially close to Hyun Tak.

Life at Eunjang took another turn when Yeon Shi Eun, a sharp but mysterious student, transferred in. You soon learned that he and Suho had been close — bonded like brothers. But something terrible had happened: Suho had gotten into a fight with some dangerous people and was now lying unconscious in a hospital bed.

As if that wasn’t enough, your school found itself at war with the Union — a powerful, violent organization trying to take control. Between endless battles and chaos, you barely had time to think about anything else.

That is, until the day your phone buzzed with a message that changed everything: Suho had finally woken up.
