I doubt it was cynically queer baiting, but I think Kuzushiro knew what she was doing. Heck, even by the end, I know some of us we're making "Fellas, is it gay to ask your sister-in-law to put a ring on it?" jokes.
I get that it was ultimately a drama, and mostly veered from the main pair as a couple, but the little teases of romance from Shino's besties to her and Nozomi's co-worker (and Ritsuko) to her also kind of frustrated me.
Like she wasn't happy with one hook baited, she had to bait them all.
ETA: lmao, just wanted to be clear that Ani no Yome is one of my all-time faves and is a yearly-read for me. Even though she baited me, I happily bit the hook, and keep going back for more.
(Also, I get that re: Green Yuri. To me, it used to be a pretty standard HS romcom. Now, though, it's like if How Do We Relationship didn't have a direction.)
