[DeepL Translation - needs review] I am a girl! A marble suddenly started talking in 16-year-old Seijun's room. Seijun had been in love with her since she was a child. Marudama is so happy that he follows her to high school. But in the classroom he seems bored. When he meets a girl at his part-time job, his heart is buoyed. A difficult boy and a straightforward marble girl interweave their adolescent love and confusion. A heart-throbbing high school novel filled with precious moments.
(Translator: DeepL)
Who wouldn't relate to a high school marble?
It's somewhat high school novel, but also with a healthy amount of absurdity, which feels slightly similar to some 今村夏子 novels.
My favourite section was probably a section which cycled through lessons with some of the oddball teachers.
