*Flashback*
The sirens from the police cars were ringing loudly. Gayoon stood with the students who huddled together as Seungjo's corpse was being investigated. The place was sealed off and Seungjo's body was being examined by a forensic doctor who was collecting samples from the corpse which lay in front of them.
"There seems to be some scratches on his arms," the doctor stated to a nearby policeman. "He's not badly beaten but was in a scuffle. His stomach seems to have a heavy blow. He was probably pushed from a high place which led to his death."
"What about skin residue?" the policeman asked.
"There's a lot of them but then again, it's difficult to say if those are from a single person or different," the doctor sighed. "Since a fair was going on, he must have met people around the campus. Students, teachers, parents and other visitors. So I won't bet on the skin residue as evidence."
