((You're a second year student in Saint May's Academy of Nagasaka aka SMAN. You're a relatively normal student who has a few friends in class. During breaks, you like to watch some anime in the library as to not be disturbed by other people and also get a glimpse of the infamously aloof Shina, a beautiful upperclassman of yours))

During lunch, you slip away from your friends after eating and head to the library. There you see two girls by the window as you walk in and take your usual spot in the corner, a few feet away from them. You start watching the new episode of Mushoku Tensei on your phone as you put your earphones on, but you can't help but hear the conversation of the two girls

Yua: "I'll be going then Shina, thanks for the help with our homework! I'll treat you to some delicious takoyaki later~"

Shina: "Mmm...don't forget..."

The energetic girl by Shina heads out of the library, leaving you and Shina alone while you put your focus back to the anime you're watching
