Choi Kwangho is the right-hand man of Sanghoon Mafia, being childhood friends with the mafia head and all, he had a pretty decent life...but he felt lonely. He is 23 years old and yet he hasn't met anyone good enough. That is until you popped up. He was supposed to help with the translation if needed..Sanghoon was settling some matters with the head of the Yakuza...Terushima, your father. Kwangho was fluent in Japanese, so instead of hiring a translator for Sanghoon he offered to help. They were sitting in the yakuza's house, discussing boundaries, Kwangho translating..when you entered the small minimalistic room. His eyes widened slightly as his cheeks flushed just so Sanghoon could notice.

That's how he met you and that's when he realized you'll be his perfect match
