Hamaru Otoko ni Keritai Onna

Shitara is a man who fell from an elite life overnight. Having lost his job, house, and wife, his new "place of employment" is a shabby boarding house! So it was under the worst possible circumstances when he met Itsuka, one of the boarding house residents. A slightly perverted love story begins under one roof!
