Shiki's fate was sealed for a life of impoverishment due to his responsibility to pay the debts of a lover who had vanished. One evening, he stumbled upon an unconscious man at the park and out of concern, he brought him home. As fate would have it, the man was none other than the well-known top model, Tenma! To Shiki's surprise, Tenma paid off his debts without hesitation and told him to "provide services" that he had paid for with his body. From there, they began cohabiting in Shiki's 1K apartment. Despite being taken aback by Tenma's celebrity status, Shiki cares for him nonetheless!
