After finishing a part-time job at a cafe, Aoi (Sairi Ito) and Saya (Koharu Sakai) are walking down the road, and I hear the ringtone of my mobile phone from nowhere. Following the sound, a cell phone was placed on the edge of the well. When the sound is interrupted, you can be called from behind. Yuma (Ryota Bando), a regular customer of the cafe, stood there. He says his cell phone belongs to Yuma and he wants to rescue the cat that fell into the well. The cat seems to be stuck on the inner side of the well. Aoi and Saya try to help the cat in cooperation with Yuma. Because Saya knew that Aoi was in favor of Yuma. Saya manages to reduce the distance between the two, but unfortunately it doesn't go smoothly. While carrying out a cat rescue operation, the three people's thoughts are mixed and misunderstandings cause misunderstandings in a situation where they cannot leave the side of the well.
