Suah, a petite, red-haired designer of haute couture, enjoys a quiet life without any twists or turns... until she wakes up, bound to a chair. The imposing figure glaring at her is none other than her roommate's formidable older brother, Seung-hyun. He's the owner of the apartment she's called home for free for the past eight years. Suah is given an ultimatum: she has just one week to vacate the premises. Despite Suah's pleading and begging, Seung-hyun remains inflexible with the upper hand. Unbeknownst to him, Suah becomes a key member of his new team, surpassing even his wildest expectations. Joined together, their paths remain intertwined. Will Seung-hyun allow Suah to stay, and can he resist his burgeoning feelings for her in a professional setting?
