it legit feels like they're writing best friends imo. one of the characters is a single dad) and the buck doesnt bother correcting her that it's not his son.

off the top of my head, the two i can think of are a comment on a livestream IN the show universe that says 'they'd make such a cute couple' and in an xmas ep, a girl dressed up like an elf says they have a cute son (? smth like that. the acting and directing doesn't land for me as them going for romance, and people's main argument for the queerbaiting thing is that the show has had multiple throwaway lines hinting at the pair as a couple. i personally went in knowing how heavily ppl shipped them and as someone who actively looks for the queerness in everything still didn't get those vibes, lol. If you liked ls (or rlly any procedural), i'd recommend giving it a shot if you're bored just to see for yourself.
