I thought this was pretty decently good overall (with some caveats), but it does feel a lot more the tropes came from a certain type of topsy-turvy seinen romance—where everyone's motives are a little imperfect, the characters wallow over issues of self-worth, minds stray periodically to the gutter, the overall worldview tilts cynical even when things go well, and you just know you won't fully grasp the love interest's true feelings 'till the end (sort of pulling the "women are a mystery" trope even though the MC is also a woman).
And as is par the course for that genre, some of the dramatic tension comes from whether you even should be rooting for this romance as it is, or whether everyone's going to come away scarred. People's uneasiness about either protagonist seems decently well-warranted, but it wouldn't be so simple to tell this sort of story if the protagonists didn't foolishly dive in to all of this head-first.
Still, I'll be the first to say that I like fluffier, vanilla-y-er GL (or romance in general) much better. XD
