Death Match!

Lee Chang-ju. 26 years old. I'm about to get crushed to death by a collapsed building, just before I graduate from college. The reason I'm like this now is because a junior I met in liberal arts asked me to go to an exhibition in this building with him, so I followed him. All my friends told me to avoid him because he looked like a murderer, but I didn't believe a single one. No, objectively speaking, he's damn handsome and has a cute personality. What makes him look like a murderer? (Source: Kidari Studio, translated)
