Don’t toy with me miss Nagatoro 12.

It’s actually happening! Senpai and Nagatoro get closer than ever before when they visit an aquarium together. But the fledgling couple isn’t alone. They’re being watched by two opposing parties—Nagatoro’s meddlesome friends who worry Nagatoro might ruin Senpai’s innocence, and the Sunomiya duo, who will fight to let love take its course. Depending on which side gets its way, this long-awaited rendezvous could become a date with destiny or a date with devilry!
