Yui succeeds in keeping Kaori away from the accident and disappears, almost as though she never existed, but the other members of the Astronomy Club are left with a nagging feeling that they are missing something.
Things are going quite a bit more differently in this timeline as Sou's interest in Yui seems stronger than usual. But even as the outcome remains uncertain, Yui ponders what the consequences will be if she succeed.
Airi reminisces about how she met Kaori and Sou. The Astronomy Club once again takes on the Judo and Karate Club dispute, with a slightly different outcome. And they also make headway on the case of the school ghost.
Sou is an ordinary high school student. His biggest worries are his Astronomy Club's project, the zany antics of his fellow club members, and his childhood friend who's suddenly not her usual cheerful self.
