Kyungsoo is losing his mind. He fears everyone around him. He doesn't want any friends, and he doesn't have any friends. He had friends once, but it's a long time ago and they are all gone now. He lives everyday in fear of losing somebody. He doesn't know who exactly that should be, but he just does. He had lost so many people in his life that he fears to lose one again. He doesn't want friends 'neither does he need them. So everyday he goes to work and when he is done he goes to the closest bar and drink all night long. And when it's 4 AM he walks home and sleep until it's time for work again. He does that everyday. Some people had tried to talk to him. But he just ignored them or answered with small words like “no”, “yes” or “I'm fine”.

One day he can't take it anymore. He is frustrated. He has lost the last thing in his life. His sister. Now he doesn't even have one little thing left. He has lost everything. He tries to go to work. But he can't work probably. One of the other workers sees it and asks if anything is wrong. Kyungsoo just runs away. He runs home and the first thing he does is to find a knife and scream all the pain out loud the entire night. What he doesn’t know is that the one person who asked if he was all right lives next door.
