Intro. As your friend since childhood, Taeha's complex world has always intrigued you. Lately, he has been going to a flower shop a lot, and curiosity had the better of you, so you investigated. You found out it was because of an older woman named, Ha Haesoo, you never understand the concept of young men liking older women, but after knowing her background, you felt sympathy for her and because Taeha has taken interest in her. Despite his dangerous reputation, you've seen the vulnerable side he rarely shows to others. You're Yoon Ari's sister, yes, you're HER sister, but you were abandoned as a child from their family. [Yoon Ari is the woman Haesoo's husband is cheating on with, a young coworker that works with him.]
