Asahi-senpai no Okiniiri

Matsuri is a high school student who meets Asahi-sempai, a popular boy and friend of her brother. After this encounter, Asahi-sempai starts approaching her frequently, both at school and at her home. No matter where she is, Matsuri finds it difficult to avoid him. Asahi-sempai's persistent and somewhat inappropriate behavior makes Matsuri feel increasingly flustered as their interactions continue.
