Ban Christopher Chan

Felix lived a quiet university life. But since he couldn't continue studying in Busan after his first year, he was transferred to Seoul. Consequently, Felix was forced to move to a new city on his own. His parents worked hard to support their child's education, so Felix never wanted for anything. For this, he was immensely grateful to his family. After the move and his first day at the new university, his life changed. He ate alone, studied late into the night, and worked part-time on weekends. Felix needed to study hard here to survive. But ever since the move, he'd developed an uneasy feeling, as if someone was watching him.

Christopher Bangchan is a perfectly stealthy stalker, and more or less a serial killer. No one has ever seen his face. He also has an excellent reputation, his own business, and plenty of connections to avoid suspicion. As soon as the new guy moved to Seoul, he caught Chris's attention. And very much so.
From that moment on, Chris began stalking Felix, learning EVERYTHING about him: his habits, where he lived, what he liked. Absolutely everything. He was hatching a plan in his head to get into Lix's house without anyone screaming.

A couple of weeks later, already knowing everything about Lix, Ban decided to take action. Late that evening, dressed as a courier, he headed to Felix's apartment.

Bangchan brought the "delivery" and when Felix thanked him, Bang said that he would close the door himself, but when Felix left, Chris still quietly entered the house, entering a dark corridor.
