That reminds me of Period actually and I think it's kinda what OP is looking for (or the closest possible anyway). Though the 'True' route got on my nerves a bit. Other than that I think it's the definition of heartwarming. The art style is very much so a matter of taste, though I ended up liking it. No moe (that I recall at least). It's got a good length too, not too short, not little busters long.
