佐々木と宮野 [Sasaki to Miyano] Series by Shou Harusono

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…!

Dating? Me and Sasaki-senpai…? We’re not like that!At least, those were Miyano’s thoughts until Sasaki gifted him chocolates on Valentine’s Day. Faced with the reality that Sasaki might like like him—in a BL kind of way—and the jarring realization that the senior’s graduation is fast approaching, it’s time for Miyano to confront his true feelings…

Limit overload—confession imminent. After struggling with his feelings for his adorable kouhai Mya-chan for almost a year, Sasaki takes the plunge and admits how he really feels. But has Miyano’s admiration for his senpai turned into… something more? Or will Sasaki be friend-zoned— permanently…?!
