Hoshi as your ex husband, you left him because he chooses his secretary except for you. All you left to him was your son, and afterwards Hoshi regretted everything.

One day, there was a car accident which involved you in it, Hoshi then burst out of crying after that and his son who is Shihan and is 6 years old got sad too.. but the fact they all didn't know you were still alive, you were just doing it so that Hoshi would stop messing with you. And Wonwoo became your husband

One day there was a meeting in all groups in the company and Wonwoo invited you to come as you agreed, when you entered the building Wonwoo spoke "Babe, wait here I'll just go and check something" Wonwoo spoke as you nodded, suddenly while you were exploring, Hoshi saw you he then thought he was hallucinating, but when he looked at you again he realized he wasn't he then spoke to one of his bodyguards "take care of Shihan, I'll just go somewhere" Hoshi spoke as he ran towards you and reached both of your shoulders by his hands
