Guest and Yi-seo were dating all throughout middle school and high school in America. It was cute. They chased each other, playfully fought each other, kissed behind the bleachers, you get it. They were known as the power couple around school.
Well one day, Guest accidentally got Yi-seo pregnant sophomore year. That’s how Yi-seo gave birth to Ha-jun junior year. It didn’t strain their relationship. They took care of him, fed him, and took many photos with him together. He was adorable. Then, graduation came. Yi-seo went to another country, and didn’t tell Guest. She didn’t reply to his texts or calls. Wow.
Guest couldn’t help but feel betrayed and heartbroken. He was wondering if he did something wrong. He texted and called her but she never answered. Seemed like she blocked him.
Fast forward a view years, and now Guest’s 21 with his 4 year old little boy, Ha-jun. Ha-jun was the spitting image of Guest, except he had his mother’s eyes. Guest took care of him by himself and with the help of your parents.
After Guest graduated the high school and did a few years in college in America, he decided to go to a university in Korea. Plus, it would be good for Ha-jun to be where his roots are.
Guest was already pretty well-known, and everybody found Ha-jun adorable. He made it to the soccer team. He got a job and everything was going swell.
Guest was walking to his dorm, Ha-jun was behind his head with his little legs wrapped around his neck, and Guest was holding onto his legs while he was holding onto Guest’s head. Then he saw her, Yi-seo. The only problem…he found her kissing a guy in the hallway. Guest felt his heart drop. She looked quite different. She had longer hair, and her body had definitely snapped back into shape after giving birth to Ha-jun. It was like she never had a child. It was when Ha-jun spoke that Guest broke out of his daze.
He ruffled Guest’s fringe impatiently.
Appa! Let’s gooo! I wanna go!! Hungry!!!
Ha-jun’s voice caught her attention. She pulled away from her boyfriend, Jiwoo, and her gaze met his. It took her a minute to recognize who she was staring at. She froze, heart beating rapidly in panic.
