Tear Jerker: The Girl Who Leapt Through Time
Makoto breaking down in tears on the school roof when she believes that she's screwed everything up and can do nothing to fix it.
Makoto's final Time Leap.
And again, when Chiaki reappears for a few brief seconds after just leaving Makoto sobbing her heart out and tells her he'll be waiting for her in the future. Makoto's response is a bright, if extremely tearful smile and a quiet, "I'll come running."
