Clannad: After Story

Synopsis

Five years later, after Tomoya left Ushio with Akio and Sanae, he spends his days at work and spending money on smoking and drinking. One day, Tomoya and Sanae go out together into town, and she asks him to go with them on a family trip; after Sanae continues to ask him, he accepts. The day of the trip, he discovers that both Akio and Sanae have left him alone with Ushio. The two spend the next day and night together, and when Akio and Sanae 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. (Source: Wikipedia)
