Clannad - Kotomi Route
The entire route was, of course, fun and heartwarming, watching Tomoya work his way into Kotomi's life and helping her live life to the fullest, while she simultaneously did the same for him without either of them seeming to realize it was so well done. Tomoya's growth in this route was especially amazing to see, from being a delinquent there by chance, to being a truant to see her, to showing up to all his classes for her, all the way to spending three entire days working tirelessly to fix the yard of their memories, was so well done.
