Long Summer of August 31 Vol. 2 (manga)

Suzuki never expected getting a girlfriend to be easy. But after facing up to his true feelings, he’s more determined than ever to woo his time-loop comrade, Takagi, even if she isn’t quite on the same page yet. He decides to shake things up with a series of dates hoping something, anything, will change things for the better and stop the loop: shopping trips, hanging out at the library, even an excursion to a theme park.

But will it be another couple’s own awkward first date that provides him with the solution he’s seeking?
