Looking for some M/M Romance books with seriousness in the plot and prose?

Hi y'all, so I'm looking for a book that is just well written and doesn't treat M/M stories like a Wattpad story written by a 15-year-old fujoshi fangirl or an erotica. I want a book with well-evolved prose and plot but not one that is necessarily tragic (happy with either but if its a tragedy it should feel natural and not tragedy for the sake of the tragedy stereotype that LGBTQIA sadly have).

I haven't read that many M/M books, but my favourite is The Song of Achilles by Madeline Miller due to how well it is written and the recontextualising of the story of Achilles and Patroclus, and some of my favourite books in general are The Seven Husbands of Evelyn Hugo by Taylor Jenkins Reid and Heartstopper by Alice Oseman because of how they talk about the daily lives of LGBT people in the past and these days, respectively, but still with maturity and delicate. I like stories that make me think, feel and remember and reminisce on it years later.

Reading The Song of Achilles and watching Heartstopper season 1 made me fix up my life by losing 40 KGs of weight and become more socially outgoing and try dating (and get a S/O) and I want other stories that have had similar effects on people due to its quality, in the writing and prose.

In other genres, I love supernatural, both sci-fi and fantasy, but nothing simple like Twilight or the Hunger Games where the romance aspect exists but doesn't have huge maturity (I know Hunger Games is much better than Twilight in that aspect but you wouldn't hear anyone recommend it for its romance specifically, if you get what I mean). I love high fantasy like A Song of Ice and Fire (currently reading the Stormlight Archives) and futuristic sci-fi as well like The Hunger Games (despite what I said about it before) and The 3 Body Problem.
