After Being Dumped By Senpai, I Met A High School Girl

I, Kotaro Hasegawa, have what you call "Onee-san Complex". During my high school, I confessed to a Senpai during my high school years and was rejected. Years passed and I'm now at college taking up a teaching degree. During my college years, I encountered a high school girl being picked up by strange guys and helped her. As part of the teaching course, I was assigned to Fukui High, where I graduated and met yet again Senpai.   Author's Note: Thanks for taking the time to read. It was my first time writing, so if you have any questions or recommendations, feel free to comment it!
