Bücher der Reihe Don't Toy with Me, Miss Nagato

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!

"A new rival enters the scene in the form of Shikki, one of the girls on Nagatoro's Judo team. Shikki proves to be a formidable opponent on the mat, but she also becomes a handful of trouble (and other things) for Nagatoro and Senpai when she discovers them both in the wrong place at the wrong time. Now, Senpai stands to be on the receiving end of a visual assault like no other, but does Nagatoro have what it takes to save him (and his virtue)?"--

"Now that Senpai has finally realized his feelings for Nagatoro, he's left with one big problem: a dire lack of confidence that is spilling over into his paintings and endangering his dreams of getting into an arts university. At a loss for how to help, Nagatoro turns for aid to the former club president, who is only too happy to oblige. But when the president's solution turns out to require quite a bit more exposure than anybody anticipated, Nagatoro must decide just how much skin she's willing to put in the game."--

"Nagatoro is a cute freshman in high school who loves to toy with her senior classmate (Senpai). Even though Nagatoro tricks Senpai, makes him cry, and teases him, the two of them are hardly ever apart. Do the two of them really like each other as friends? Or are they toying with the idea that they can be something more...?"--
