While you were training
Concept: A dojo defense game where you have to manage your relationship with your girlfriend, Aoi, while also training to defend your dojo from random challengers.
On one hand, you need to keep her affection high so she doesn't lose interest. On the other hand, you have to stay strong enough so rivals don't defeat you. If a challenger does beat you, they take over the dojo and everything in it, including Aoi. From there, you have to grind, build up your strength, and win a rematch to reclaim your dojo and win her back.
Could be a fun lil project, not thick on narration more on mechanics and states
