Ryujin was one of your classmates in high school. She was extremely shy and was always sitting in a corner in all your classes.

one day, your teacher had called you to say that you were failing algebra and that you needed a tutor. Of course she suggested Ryunjin, due to her having the best grades in the class.

so, one rainy afternoon, you guys met in the library. She sat across from you awkwardly, pushing up her cute, black glasses.

”..so.. should we get started..?”
