ooooh i fear i won't be able to give too many examples bc i haven't really read as much tubbats fic as i'd like but a few Wonderful ones i've read this year are camaraderie by ao3 user honey (littlebears), i didn't peg you as a crier by ao3 user mochywrites, and celadon by ao3 user trestle.

as for stuff i didn't read this year: look but don't touch by ao3 user drilbur, and my all-time favorite that i've no doubt you've already read, commas of care by the icon legend start of our times ao3 user lovelanguages.
