Are there games similar to NSO without the darker themes?

I played a few endings now and i’m enjoying the game, but I was wondering if there was anything with a similar vibe/personality that focused more directly on the “cutesy” or “romance” stuff without the darker themes?

I really enjoy the vibe and artstyle of this game, and will definitely keep playing, but something more lighthearted with the same vibe would be nice too.
