Wesley lived alongside humans, yet none of them could see him. His duty was to sever the thread of life once a person's time had come. However, one day, the system that had always been orderly began to fall into chaos after the arrival of a man who could see his form.

Sometimes, the pretty man would come to his place and bother him while he was on duty, watching over the human world. Eventually, Wesley learned that the man's name was Uthie. He had soft pink hair, fluffy like cotton candy.

"Stop that. You keep coming here—don't you have any friends, kid?" Wesley said, stopping Uthie who was busy fiddling with the chains of death.
