One day a new student named Mikoto Urabe transfers into Akira Tsubaki’s class. She’s bizarre in every sense of the word, from her appearance to her behavior. When she leaves after falling asleep in class one day, Akira tastes some of the drool on her desk -- and becomes totally addicted! In fact, without it, it seems like Akira gets feverish from withdrawal!

Mikoto finds out, and begins to give him a daily taste of her drool. Soon enough, they get to know each other better and Akira finds out even more weird things about Mikoto’s life and her hobbies (like carrying scissors in her panties!). Then Akira confesses to her, and thus begins their bizarre hormone-drenched romance!
