Mr. Hoshi is the homeroom teacher of 2nd Year Class 4 at an average Girl’s School. He spends his days baffled by the puzzles his students doodle in their class diary, forced to take care of the dog someone brought to class, giving advice to a student who wants to be a manga artist, and occasionally going for drinks with his co-worker Mr. Kobayashi. The daily life of this awkward teacher is both endearing and amusing. Experience a hilarious slice-of-life story unlike anything you’ve seen before!
