"Nagatoro is back and toying with Senpai more than ever...and the two only seem to be getting closer to something more than "just friends." Armed with a lollipop, a bathing suit, and an ear-piercing gun, Nagatoro just might send Senpai--and herself--over the edge."--

Nagatoro, a freshman, teases her older classmate Senpai to no end, yet she can't stay away from him. Senpai gets embarrassed by Nagatoro, yet he can't stop thinking of her when they're apart.

"New year, new nuisance! Nagatoro and Senpai open the year at a shrine famous for matchmaking, hit the slopes for a school ski trip, and do some sparring at an MMA gym. But will these new events bring Nagatoro and Senpai closer together, or will Nagatoro's chaotic kidding spell K.O. for their pairing?"--

"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...

The moment of truth is finally here, as Senpai's mock exam and Nagatoro's judo tournament get into full swing. With so much riding on the results, the two buckle down for the fights of their lives. Will Senpai draw his way to the top and win the right to tell Nagatoro his feelings? Or will that dream, and the promise he made with Nagatoro, go up in flames?

"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)?"--...

"The trolling rolls on with Nagatoro! But who exactly is she? For all the time that she's been pestering Senpai, he doesn't really know that much about her. But that changes when he checks up on Nagatoro at home while she's out sick. There, he meets Nagatoro's older sister, who teases Senpai with the chance to learn Nagatoro's deepest secrets"--

"Lions and tigers and badgering, oh my! Nagatoro takes her teasing outdoors when Senpai asks her to join him at the zoo. The thing is, she thinks their outing is an invitation to go out! Senpai wants to enjoy a plein air sketching session, but what will happen when Nagatoro finds out that their date is nothing more than a plain error?"--

"Winter arrives and Senpai comes down with a cold! But even Senpai's rising body temperature won't stop Nagatoro from getting a rise out of him. With Senpai absent from school, Nagatoro decides to pay him a visit at home, but things get a little heated when Senpai's feverish state makes him imagine Nagatoro in a strangely domestic role..."--
