I’m Kouta Koikawa, and I’m having a problem with my studies. It’s not that my classmates’ ruckus bothers me, I sit at the front of the room to avoid their antics. The real problem is my social studies professor, Chieri Hase. From the day she started teaching here I have not been able to keep my eyes off her! She’s a rookie teacher, but I’m captivated by every movement of her beautiful body. I can not work up the nerve to confess my feelings – I’m her student, after all, and I’m sure she would not find this sort of forbidden love to be proper … until one day when fate brings us together in an encounter that changes our lives forever.
