the uke gets pregnant by the alpha but the guy never let the father know, now they meet again because the uke is selling soup on a food truck and the guy is an executive. The alpha thinks the uke is selling his body so he pays a lot to him to be the only one client (but he was just a massagist). Now he knows he has a son and is trying to marry the uke
