YES it has happy endings, 9 of them if you include the poly romances and the no romance ending :]
This is something we’re also really passionate about because why should you pour 10+ hours into a game and grow to love the characters just for it to end in misery, right? So yes, you can have a happy ending AND there are even DLCs post-ending with even more happiness for you to indulge in.
We made sure that the choices you make are very well labelled so you don’t stumble into a bad ending also, but if you’re unsure please feel free to contact us and we can nudge you in the right direction!
