It's ABO alpha X alpha, and the older brother (beta) wants to kill the younger brother (alpha) because he doesn't want him to take over the company. So he constantly is trying to ruin his image, and he has him date a guy so their homophobic grandfather will hate the alpha grandson. BUT, the grandson gets into a contracted relationship with a super rich alpha so the grandfather's hyped, and the person he's in a contracted relationship with is abusive towards him. Can give MUCH more information if necessary.
