On the way back, Ryoko leads Yuki to realise that she has fallen in love with Kyon, leaving her even more fearful about her inevitable disappearance. Sensing the next time she falls asleep will be her last, Yuki spends the day with Ryoko, keeping her disappearance a secret from her. Later that night, Yuki confesses to Kyon over the phone, falling asleep by the time Kyon reaches her, after which the original Yuki wakes up in her place.
