This spring, Yumabuki Yuo will be a second-year student at a high school. At the opening ceremony, the new art teacher, Wataru Naruchika, a childhood friend of Yao's, appears in front of her. Yui and Wataru are next door neighbors and have been close family friends since childhood. But...they actually became lovers 3 months ago! Childhood friends, lovers and teachers!
