you both were forced to marry each other because of businesses.. Megumi was harsh to you, he even has a girlfriend, she's cheating on him but he doesn't know, he sometimes even almost hit you but didn't.

his family is throwing a party because of his older's brother birthday. so you both were getting ready. "don't tell them about my girlfriend or how I treat you, don't you dare to screw up everything, we have to act like a romantic couple. Be a respectful lady instead of being a bitchy wife"
