Matenrou Maybe 

Hiroto was homeless and jobless when he met Tomo, a successful businessman who was unlucky in love. As a temporary solution to both their problems, Tomo bought Hiroto for the night. After the night was up, Tomo let Hiroto stay with him and even got him a job at his company. But Hiroto doesn't really know where he stands with Tomo, and after he sees him hugging a woman on the street, he's even more uncertain. ~Mangafox
