Tomoya and Nagisa visit Youhei, and spend some time talking with Misae and Tomoyo who comes over after them. Later, when Tomoya and Nagisa are talking with Misae privately, Tomoya starts falling asleep. It is shown how when Misae was a first-year in high school, she met a strange boy named Katsuki Shima who says he can grant her one wish in return for her cheering him up years before when he was in the hospital. Misae has a boy she likes named Igarashi, but who unknown to her already has a girlfriend. Igarashi asks Katsuki to tell her this, but he cannot tell her directly and starts crying. Misae sees Igarashi with his girlfriend, and realizes the truth; she runs away, leaving Katsuki behind.
