I've only picked the show up this weekend and haven't watched the last three episodes, but it's been so nice and chill.
Also the opening's a banger and the artstyle is super comfy. Not something I'd have expected from Pine Jam.
I loved the completely uncommented look into Serufu's room relatively early in the show, where we saw quite a few trophies, awards and what looked like certificates in her room. Assuming those were hers, it was clearly foreshadowed that there's a lot more to her than one might initially think.
HOWEVER! That picture is so unrealistic, she doesn't have any band aids on her fingers and arms (that we can see) and only one on her nose! When's that ever happened?!
