Question about The Promised Neverland to people who have seen it

I'm currently watching Season 1 (8 episodes in) and don't want any spoilers, but I want to know:

1. Does the series conclude at the end of Season 2, or is it still ongoing?

2. If it has concluded with Season 2, does it have a "happy" ending? I don't need a save the world ending necessarily, but at least a "some people safely escaped" ending with some feeling of catharsis rather than continuing despair and doom. Don't tell me what the ending is; just the general mood of it, I guess.

On the one hand, it's giving me fun cleverness vibes I haven't had since Death Note, plus exciting interesting mysteries. On the other hand, I'm depressed enough as it is irl, and the feeling of unescapable doom is a bit overwhelming.
