Sunghoon and y/n were highschool sweethearts, they were together all throughout highschool and were voted most likely to get married to each other. But something happened during their third year of college causing them to break up. It wasn't messy but it wasn't clean. A few years passed by, and both y/n and Sunghoon graduated with flying colors and made it far in life. Though they both never got over each other and haven't dated since their break up. Sunghoon became the CEO of a well known company while y/n became a well known Doctor. While at work y/n met a man, he was kind hearted and almost everything she could want in a husband... But she still wasn't over Sunghoon. Y/n knew that Sunghoon was doing well and she thought he had gotten over her long ago, so she thought that if she married this man she'd get over Sunghoon. She knew deep down that she would be wrong. Fast forward present time... y/n is in the brides room getting ready to walk down the aisle, when suddenly... Sunghoon barges in. He looks stressed and almost in tears. The moment he saw you his gaze softened. He's breathing heavily cause he was running. "Don't marry him..."
