Yen Press releases the Sasaki and Miyano manga in English and describes the synopsis as:
It all started like a typical old-school boys’ love plotline—bad-boy senior meets adorably awkward underclassman, one of them falls in love, and so on and so forth. But although Miyano is a self-proclaimed boys’ love expert, he hasn’t quite realized…he’s in one himself. Which means it’s up to Sasaki to make sure their story has a happily ever after…!
