Doushitemo Furetakunai, Conveni-kun. Recommendations
On Shima's first day at a new company he meets a drunken man in the elevator. It turns out this is his new boss, Togawa. He's rude and crass, but has a kind underside.
This manga has a similar domestic setting. The characters each have some emotional damage, but have their charm. Art is different from the usual yaoi, but very good. It's pretty short, but is worth a read.
