There was a yuri manga where it starts with a middle schooler going on a high school tour I forget what happens but she meets a senpai and the senpai gives her a tour and the middle schooler somehow gets the senpais handkerchief. Then when the middle schooler gets to high school she wants to return the handkerchief but the senpai starts ignoring her. I don’t remember the name of the manga so if anyone knows that would be helpful.
