Trying to find manga

But I literally don’t know how to explain it all I know is that it’s An abo and the omega is I think kind of like muscular and in one scene they (rich parents I think) find an alpha (he’s handsome and pretty blonde haired guy) for him and when the mc goes to the omegas house he finds the alpha there and thinks the omega doesn’t like him anymore I think but turns out the alpha and the omega just were friends and that’s all I know LOL
