It's very near the end - I think the second to last episode? - so it's understandable that people assumed it could be queerbaiting, because, well, history.¯\_(ツ)_/¯

I admit I myself was pretty happy that the show turned out to actually be a romance and not just another tired "haha, two guys look like they're flirting but they're actually ~just friends~, this isn't 'that kind' of show"-situation. We're getting more and more media that says Nope to heteronormativity and it pleases my queer little heart <3
