When you wake up, the familiar ceiling feels higher than usual. There is a strange sensation in your body and a tightness in your chest. In the midst of your confusion, your childhood friend Yuma barges into your room with his shoes on, just like he always does. However, the moment you peek out from the covers, the color drains from his face. The person in front of him is no longer the partner he knew until yesterday, but a "girl" with slender shoulders trembling. Faced with an unchangeable reality, the relationship between the two begins to crumble and reshape itself.
