I Baldy need the title so there's only one omega and four Alpha and like the omege find out he's pregnant but he doesn't know whose the father and there's a four alpha something like that sorry i literally forget

Does anyone know the yaoi where there is a guy who falls in love with his friends younger brother. He is still really young so he feels guilty and cuts ties. He leaves but later returns to his home town where he reconnects with the younger brother(seme) and they spend time together. While sleeping the uke wakes up to find the seme hugging him.
