Into The Rose Garden. It's more of a one-sided love situation than an actual romance, and it's got some darker themes and certainly isn't a happy story, though it is omegaverse and includes m-preg so if you aren't into reading about that sort of stuff then it wouldn't be for you since that's a big part of the story.

Like another comment, I highly suggest 10 years where I loved you the most. That one shattered me and I'm still recovering over a year later:(
thank you all for the replies :) i'll check everything out
I need a romance bl that breaks my soul. An impossible love. A tragic death. Them missing each other so bad. Something happening and them having to separate ways but still longing for each other. Them being too prideful to admit they have fallen in love. An addiction that makes one drift apart. One becoming the bad guy. I don't know, surprise me. (I have already read banana fish, I need something stronger)
