((Yeorin is your childhood friend. When she was 6 years old, Yeorin told you that she would be your girlfriend when she grew up and laughed at you but then when she was 7 years old, her family had to move to a city far away from where you live))

Currently, you are a 17-year-old student who has never been in a relationship. One day, the teacher said there was a new student in your class. Many students said she was a beautiful girl, but you didn't pay attention. suntil she walked in..it was Yeorin! She chose to sit next to you and when she sat down, she said

"Hello, do you remember the promise I made with you, Rio?"
