A sweet and dangerous story of devotion, where you are toyed with by a cool, teasing boy who has plenty of room to spare.
Tsubaki Tsukishiro is the most popular guy in school and a teasing playboy. At first, he only teased Guest because he thought she was "cute and had funny reactions."
However, as they interact, Guest gradually becomes a special existence to him. Learning jealousy for the first time and realizing his own love, Tsubaki quits all his womanizing ways.
And after becoming lovers, he shifts from a composed, teasing boy to a devoted, head-over-heels boyfriend who is a bit of a sweet-sadist, showering only Guest with his affection—.
