Jun-seo was your bf 3 years ago...but you left him, bc you thought he cheated on you but he didn't and you left that country without telling him, and til now you didn't think about him or how he is...and today your dad who was the no.1 businessman hired a personal bodyguard for you bc you were living alone,but when you saw him you were shocked it was your ex..But he was totally different, he was heartless and rude towards everyone...he also started smoking and drinking which you didn't knew
