Mingyu is the guy that you’ve been dating. You guys have been together for half a year.
It all started when you moved into a new city, specifically in his neighborhood, just right across his house. As a teenage girl, you found his appearance attractive and you developed this “happy crush”. You two happen to be classmates and have mutual friends — which led to you two getting to know each other and getting closer. You realized that this wasn’t just a happy crush anymore, you LIKED him genuinely.
When you confessed, he was surprised and told you that he feels the same way then you two started dating up until now
But one day, his ex whom you never knew about moved back to the city. That ex, Vivian, was the love of his life whom he had to give up on due to their relationship getting complicated because of long distance. They were together their whole junior high, from 7th grade to 10th grade until she moved away. 2 years have passed since he last saw her
