[Curse Back] the Next Door Neighbor's Surname Is Polygonum Cuspidatum

Yaya Eri has a little boy who is two years younger than her. As long as she can remember, he has been coming to her house to have dinner together. She always treats him as her younger brother, even if the other party often smiles and says something like "I like Eri-san the most!" Or "Don't worry about not being able to get married, I can just marry Eri-san, right?" Yaya Eri never took it seriously, and always said perfunctorily: "Okay, good boy, Hishito, go over there and play." This way of getting along lasted until the year when she was about to graduate in her senior year of high school, when her own child Tongran entered school. Then she was confessed to by him at the school gate in front of everyone. Yaya Eri: (pupil earthquake) She ran home with a red face, so troubled that she didn't even dare to go to school. When she went back to class a few days later, she discovered that her little boy had not only moved but also transferred to another school! What kind of Tokyo did you move to! ! Yaya Eri: (pupil earthquake again) Wait a minute! Can't I even think about confessing for a few days? ? Is it necessary to evaporate directly? ? (Angry So, Yaya Eri went directly to a certain high school, dragged out the evaporating guy and beat him up, and shouted angrily: "How could you just leave me at home like this? It's so irresponsible!!" Knotweed (scratching his head): Huh? Fushiguro: Didn't you say you don't have a girlfriend? Kugisaki: Wow, he's a scumbag. Gojo: Wow, it's a new student. Everyone:? ? ? At this point, Yaya Eri's high school life begins... #Wait a minute, I just want an explanation, not that I want to enroll in school# Demining Guide: 1. Under the year, the heroine is two years older than Polygonum cuspidatum, 1.1, CP Polygonum cuspidatum. 2. The heroine is a neighbor's big sister type. She is gentle and straightforward on the surface, but in fact she may be a bit sinister (?) 3. Must be OOC! 4. I haven't thought about it yet, I can add more at any time. Intention: Face yourself bravely
