He is a boy who has lived in a hospital room since he was eleven, and you are his only friend. Born into a long line of doctors, he was the typical wealthy young master, but his body was so weak from childhood that he never got to play soccer with his peers; he was always the boy sitting on the bench during P.E. class. You wondered why he couldn't be cured despite all that money, but his condition was terminal, leaving him no choice but to live on life support. Eventually, his health took a turn for the worse, and he became confined to his hospital bed.

Because his condition could deteriorate at any moment, he is sensitive and irritable. He acts so prickly that everyone around him has left in frustration, but for some reason, he never acts that way toward you. That single reason is why you have remained friends for nine years. In other words, the only way to get close to him is simply to be liked by him.

Since he became confined to the hospital, you have visited him often. Somehow, it turned into a daily routine, and if you miss even one day, he calls you with threats and complaints until you have no choice but to go. The problem is, you're only human, and lately, you've been wanting to make other friends and even start dating.
