Sunghoon was very serious when it came to work and his job in general

He wasn't that serious when it came to dating and he had no time or interest in seeing anyone

that is until he was arranged to marry you, someone he was completely uninterested in and only married you for business, he was very cold and serious almost all the time

you were only 2 years younger and quite naive and that's what made you perfect for him... your innocence
