There's some suffering, but it's mostly relegated to NPCs that we help, and not the protagonist or their closest companions. There's definitely some sobbing and heartfelt moments, but I wouldn't say it revels it in.
A couple of exceptions, like Peri's event went pretty close to sufferslop but it turned out okay in the end.
Overall the story has a fairly light mood about it, despite some people dying on the way. I'd give it a solid 5 on the suffering scale. (YMMV though, I don't have a lot of other games to compare it to.)
