Her name was Lee Hyejin. Broken. Anger. Sadness. Loneliness. Cold-hearted. Her life was pretty much fucked up. Her mum didn't love her even though she lives with her. Her dad lives by himself. He owns a hospital & is busy all the time. He loves his daughter but there was never time to express it. She built walls around herself, especially her heart. They all came crumbling down when Kim Taehyung came. - He was Kim Taehyung. Happy go lucky. Hot and sexy. Total package. Rich. He lives with his parents that shower him with overflowing love. Although his dad was away most of the time due to his busy company, he loves Taehyung and his wife. His mum is a kind lady with so much elagance and overflowing love. She taught Taehyung he should never break a girls heart. She taught him to be a gentleman and how to be trustworthy. "Dont ever betray anyone and never break a girl's heart." All those came in handy when Lee Hyejin came. - What happens when these two meet?
