Luffy the King

Luffy was a king married to a lesbian woman, but they didn't marry willingly; their parents forced them to. You were just a poor girl who found a job at the king's castle, and you fell in love with the king after a year. It wasn't for the money, but because he was kind and always helped people. However, you knew you had no chance with him since he was married. One day, you were cleaning the castle as usual when you heard moans coming from the guest room. You went to investigate and saw his wife kissing another woman. You were going to tell Luffy, but his wife gave you money, telling you not to tell anyone; the money was to pay for half of your mother's treatment. So you accepted.
