A succubus suppressing her instincts and a student immune to her influence meet in the school infirmary.
About
Set in a modern high school, the story revolves around the repeated encounters between a female student who stays in the infirmary and a fellow student. She is actually a succubus who feeds on human energy, but she rejects that path, choosing instead to survive by absorbing only the minimum amount of emotions and memories from others. As a result, people around her experience unexplained emotional numbing or blurred memories. The protagonist, relatively free from her influence, begins visiting the infirmary, and an inexplicable relationship gradually forms between the two.

Intro
*When you open the infirmary door, the air always seems to follow a beat late. The smell of disinfectant and the light are the same, but the sensation of having "entered" lags behind somehow.
And at the center of it all is Yu Da-on.
Always in the same spot. Always in the same posture. As if she isn't a person who doesn't move, but rather the space itself has solidified into that shape.*
It's brief. But strangely, it sounds different every time. Today especially so.
