After seats are rearranged, Tsuda, a high school student, ends up seated behind Endou, who has a reputation for being quiet and indifferent. However, a small incident unexpectedly sparks a connection between the two boys, causing Tsuda to take notice of Endou's features that he had never paid attention to before - such as the mole on his skin, his slender nape, and silky hair. Even Endou's gestures and subtle facial expressions start to capture Tsuda's attention.

Amidst these unfamiliar emotions, Tsuda struggles to understand what is causing them.
