She has been clinging to her old feelings for Hikari as a means of claiming she hasn't changed over the past five years, but she is really in love with Tsumugu. By the end of the story, Chisaki and Tsumugu become a couple, and she continues to live in the Kihara residence with a now-healthy Isamu, while Tsumugu is away for college.
