Looking For Yaoi Manga

ML and MC are both chaebols. MC is in sort of a succession battle with his brother and he doesn't want to be cause he loves his brother even though his brother kinda wants to kill him so to get out of the succession game he tries to fake date a guy cause they have a homophobic grandpa. ML is gay and MLs grandpa says he can be in a happy gay relationship ONLY if his partner is of his caliber. So they fake date.

Does anyone know any similar BL as like Love Tractor or Killer Crush? Beefy bottom, non toxic, doesn’t have to have sex scenes but the bottom needs to blush

The mc dated the ml's twin. (Mc is a beta? And ml is an alpha) The ml's twin eventually finds his fated pair and leaves the mc in front of the omega. The mc meets the ml and is scared to date because ml is also an alpha. Ml has the same fated pair as ml's twin but still stays with the mc.

Please lmk if you know this!
