Raise the Fake, Reward the Real

We have weird rules set in place in this home. 1. Ethan's opinion is the one that matters the most in all events. 2. If Matthew has any objections, please refer to the first rule. Ethan Moreno is the real heir who has been reunited with the family. I am Matthew Moreno, the fake heir. My adoptive parents claim that they've set up these rules because they are worried that Ethan might not feel at ease when he's home. That's why when Ethan asks to move into my room, I let him have it. When he demands that I give him my scholarship, I give it to him obediently. When he tells me he wants to marry my fiancee, Holly Nottings, I agree to it. Even when Ethan plans on using our family's account to donate ten million dollars to a university in exchange for an exchange student slot, I agree to let him have his way as well. After all, when I refused to give Ethan what he wanted in my previous life, he threatened to commit suicide after he got his sorry ass dumped by Holly. When my adoptive parents found out about it, they strung me up and had me whipped for three days and nights. By the time I was released, I was already reduced to a shriveled-up corpse. When I open my eyes once again, I hear my adoptive father claiming that he'll wire ten million dollars from the family account to Ethan.
