Shinada An

An is Takumi's mother. She runs a guest house called Fuku-An, and seems to at least sometimes work at Nagomi Diner.

Shinada Monpei
An met Monpei when she was 23 and he was 19. He showed up famished at her guest house, so she, with his help, made him something to eat. He ended up working at the guest house, and the two eventually fell in love. Monpei attempted to quit his job, but the two were so in love that he decided against it.
