Death Match!

I am Changjoo Lee. 26 years old. I am about to graduate from college and will be crushed to death by a collapsed building. 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, so I followed. All my friends told me to avoid him because he was a murderer, but I didn't believe any of them. No, from an objective point of view, X is handsome and has a cute personality, but where is it that he is like a murderer? But I... should have believed that... Me?
