My Brother Ruined the Family with His Strength, but I Cheated on Him Secretly

Growing up, he could get almost everything he wanted - limited edition sports cars, antiques from auction houses, and even the most difficult girl in school. But there was nothing like this secret, indescribable "sense of control" at this moment, which made his blood feel hot. He took a sip of wine, and the ice exploded in his throat. With this cheating ability, no matter how prodigal my brother is, I can turn him into a business genius!
