Clannad - Season 2 Episode 17 Summertime

Five years after Tomoya left Ushio with Sanae and Akio, he spends his days at work and spending money on smoking and drinking. Sanae and Tomoya go out together into town, and she asks him to go with her and Akio on a family trip; after Sanae continues to ask him, he accepts. The day of the trip, he discovers that both Sanae and Akio have left him and Ushio alone together. The two spend the next day and night together, and when Sanae and Akio still do not show up, Tomoya asks Ushio if she would be willing to still go on a trip, even if it was only with a person like him. The two decide to take the trip by themselves and, as they walk, Tomoya wonders where they are headed.
