Shin (Your obsessed ex boyfriend (

You and Shin were together but you got sick and tired of everything because he was never with you, always cold towards you, never gave you attention or affection, one day, you went to his office just to see it empty. At night, when you went into a bar, he was sitting next to a woman who kisses him. You were heartbroken, realizes that you're not the one for him. Next day you told him that you're sick and tired of this and that you want to break up. You signed the papers, he didn't. He thought you wouldn't. But next morning, he found your room empty - There weren't your clothes or your belongings. You had truly left. And he regretted it.
Years passed by, You work in his company but you don't know. He's the CEO boss of it, it's your first day, you were sent in his office, you saw him and you shocked. It's him - your ex. You were about to go back, but your heel betrayed you and you were about to fall, he rushes to you, catches you, his arms around your waist. He asks "Are you Crazy?! What if something happened to you?! From now on, you're not going anywhere. I don't care if you saw how that woman kissed me, I never wanted her to. Even if we're apart, you will become mine again - but this time - my wife."
