In any case, Kotomi also mentions how there might be a number of other worlds, and this reminds Tomoya of how Ryou had once talked about there being many possible futures. This triggers a memory in Tomoya of the role Nagisa had played in her high school performance, but he can’t figure out why. She tries to explain how their world and the hidden world are deeply connected and have influences on each other, and that leads Nagisa to wonder what the hidden world is like. The group then talks about how Tomoya and Nagisa are so far ahead in life compared to everyone else, and the topic of life prompts Kotomi to bring up her research about the hidden world. Tomoya doesn’t have an answer about his feelings, but he does know that this happened because he’s with the person he loves and is living for her sake. At one point, Sunohara asks Tomoya what it feels like to become a father, and he reveals how he always felt that becoming a parent was something in the future and something that happened like a natural disaster.

Sunohara, Kyou, Ryou, and Kotomi then visit the couple during New Years, and the group gets caught up on how all their other friends are doing. Despite this, Tomoya and Nagisa spend a happy Christmas and birthday together, and he gets her another stuffed dango to go with her collection. Sanae, however, feels that they can’t think about such things. Tomoya is wracked with doubt, and he one night talks to Sanae about how Nagisa would be living a different, potentially happier life if she had never met him. In the real world, Nagisa’s pregnancy is progressing through the months, and Sanae and Akio are helping out where they can. In the illusionary world, the girl who can no longer help build the flying machine wants the robot to stay by her side forever, but the robot knows that he has to go back out for that to happen.
