Help me find this pls

i don't remember much except that it's a bl omegaverse in which the mc is thrown out of his house for being an omega (or maybe another reason i don't remmember), his butler comes with him, and he goes to live w another rich family, and falls in love w the alpha young master and has twins with him one boy and one girl, and the alpha's butler (also alpha) falls in love with the omega's butler (beta), and they also have a kid together, and the alpha's butlers dad the head butler apparently took care of the beta butler, and they knew eachother before his son fell i love with the beta butler. Overall it's extremely sweet, and no rape. It's all in black and white i'm not sure if that helps tho
