One night, he discovered a man who had collapsed at the park, and since he was worried about him, he took him home with him. The collapsed man ended up being Tenma, an extremely famous top model!! Tenma quickly hands the debt collector a large sum of money in front of a surprised Shiki and tells him "Provide service with that body—that I bought!!" and moved into the 1K (1 room + kitchen) apartment where they started living together.
