Kohta Sato's childhood friend, Ryo Katagiri, loves Kohta's tears. He licks them any chance he gets and says rude things just to make Kohta cry. One day, Ryo challenges Kohta to a battle over tears... which aren't the only things that get licked! In addition to this tale about a sadistic top and silly bottom, this book includes stories about a teacher and his former pupil, and a lightweight drinker and sommelier! (Renta!)
