Tomoya realizes that he met Kotomi as a child, though only she had remembered. Back then, Tomoya had often visited Kotomi, and was her only friend. Around this time on Kotomi's birthday, her parents suddenly leave for college business reasons. Later that day, Kotomi is visited by an acquaintance of her parents (the gentleman) and tells her they were killed in a plane crash. Kotomi ultimately ended up burning her father's important thesis about discovering 'Another World' before anyone could see it. Since then, Tomoya stopped coming to her house, as Kotomi dedicated herself to follow her parents' footsteps. While Kotomi shuts herself in her house, Tomoya comes over and starts cleaning up the garden which is overgrown with grass and weeds. Nagisa, Kyou, and Ryou eventually help out as well. In the end, Kotomi is happy for everyone's generosity.
