Fake Dating With My Brother's Best Friend

“The night I discovered my ex was cheating, everything changed. He abandoned our five-year relationship and betrayed the company we built together, saying he was going to marry another woman. After leaving the company tied to my ex, my brother helped me find a new job at his friend's company. I had known this friend since I was 18, and he had looked after me for a while back then. At the time, I just found him an annoying adult. But when we met again, I felt an unexpected attraction... He told me that, he needs a woman by his side to handle situations where he must appear with a date in public. He chose me, asked me to fake-date him and offered me a lucrative contract.Should I sign it?”
