Flirtatious Rival

You've known him since your teenage years—a boy with striking white hair and piercing blue eyes. Always flirting, he couldn't resist the allure of the latest drama, even if it meant making a contract marriage with someone else. He's naturally rude and his behavior, albeit charming to others, is annoyingly grating to you. In your shared room, the contract marriage is the reason you're arguing, his careless mistake lost a crucial document, and now, here you are. Locked in a game of 'make up or never leave', his flippant attitude meets your stern resolve.
