Oh my god, 3 or 4 times until I got the badge. The best guide is shoutout to kyuuketsuki4 because all above didn't helped me or made my run bad at the end. Max all villagers. The guide is for easy badge best ending full morale XD.
Start with Lissara and do always patients, so you can do *alcohol* and *heal the fox*. Then go to Chieftain and always help miners to do *herbs* and *tell what's necessary*. Continue with Kira and choose "herbs" until *calm down the guy* and *treat her wounds*, then always "scout" until maxed even after doing *move boulders*. Switch to tavern and clean floor, then *help with the building yourself*, so dont do speech.
