Synopsis:
This story follows Kuwabara-san, the ace of the Swimming Club, in Gakkou de Seishun. Always staying late for training, Kuwabara-san manages to escape from everything around her when she meets with "I-kun." In these moments, she gets caught up in the pleasure of having her nipples teased, showing her erotic and tsundere side...

Even in her vanilla route Kuwabara is a super M.

Shouldn't the title be "Kuwabara Hazuki's Pure Love Route"? "School in the Spring of Youth" is the title of the main series. :/

Yes, even the afterword page on page 30 confirms this.

Pure love route is a what-if story so you don't need to read the main series to fap to this one or Ayane Pure Love route.
