The day before Valentine’s Day, the Literature Club is holding no activities. While Haruhi drags Kyon around for her own activities, Nagato makes a Valentine gift to give to Kyon with Asakura's help. But can she muster the courage to actually give it to him?

Yuki keeps having a dream in which she gazes into the memories of her other self and starts realizing that the time for her to go back to her other self might be approaching.

After Yuki goes back to being her old self, the lives of the North High’s Literature Club members are also going back to normal, except for Kyon, who doesn’t know how to deal with the old Yuki due to the knowledge of the other Yuki’s feelings towards him.

The summer is almost over. Ever since the other Yuki disappeared, Kyon has been acting strange around Yuki. When he realizes that it’s not just him who’s feeling awkward and that he’s making Yuki suffer, he decides to do something about it.
