Game doesn't have a good ending as of now. It is a sandbox and you can continue playing as long as you want.

Honestly, I think not having an ending would be better than having one, anon won’t be lonely as if before unless you mess things up and you get to spend as much time as you want with jun, an ending would be.. you know an ending to getting to spend time together with jun, wouldn’t that be sad? I mean you probably wouldn’t expect something like “they happily lived ever” you just live it and I personally like the idea of being Anon himself.
