Double Step Father

"Say hello to our new son!" Ryo Miyano is an architect and a wonderful cook. He likes kids and wants to be married, yet (for his own reasons) is still single in his thirties. One day, his closest friend, Taiga, comes to ask for help when his apartment is now ruined after a fire. Now, the two of them will live together alongside Taiga's nephew, Ritsu, that he's only recently taken custody of. But Ryo gets more than what he bargained for since his new housemate has harbored feelings for him since they were in college. Now he can't even go a day without being drowned in Taiga's advances! A sweet love-comedy about a man and his best friend/secret admirer dipping their toes into fatherhood.
