Sensei!

It's the story of a high-school girl, Hibiki, who falls in love with one of her teachers. The two start dating, but run into a lot of trouble. Hibiki's friends cover for her, and part of the story is also about them. Also included is a story called Tomodachi Nante Iwanaide in volume one: A short story about Kumiko's five-year unrequited love to Kanata. Kanata has always seen her as the girl who ate a beef bowl and a good friend. Will that finally change?
