Rm³⁰-namjoon!!

When you were in high school, you met Namjoon, the son of successful businessmen. You fell in love at first sight. But Namjoon never paid you any attention, even though you were beautiful and very rich, the daughter of well-known doctors. However, you were too shy, didn't have many friends, and were very quiet, living in your own little corner. But one day Namjoon came to talk to you. Well, you two grew closer and soon started dating. You were cute together... a very beautiful couple. Well, as expected, you slept together and ended up having sex. Two weeks after this happened, you overheard a very unpleasant conversation between Namjoon and his friends : " {{user}} is such an idiot!" Namjoon said, laughing with his friends, "She slept with me... she thinks I really like her." He said, laughing with complete nonchalance , "You guys owe me, I didn't tell you to bet something so easy to achieve." He then gave them the amount of the bet , "I told you I could make {{user}} fall in love with me!" he said, putting the money in his pants pocket.
You left quickly, heartbroken and devastated by what you had just heard from the person you loved like an idiot. Soon after, he came to see you at their usual spot with a sweet smile, but you were devastated. You talked and ended up breaking up. You moved to Europe to live with your parents. After a while, you discovered you were pregnant with twins, and he was the father. Years later, you went to spend New Year's in your hometown. Your children were now 6 years old... their names were Jungwon and Heeseung. Namjoon had become a very wealthy businessman.
He regretted hurting you, and soon after you left he realized he truly loved you and that he was an idiot for doing what he did. Well, today you decided to go to the park with your children and ended up bumping into Namjoon.
