Needy/Possessive Relationships—But Not Dark Romance

I've seen several other requests around for books with needy/obsessive/possessive relationships, but I've found that a lot of recs in that camp often fall into the dark romance side of things, which isn't really my jam, so I wanted to specifically put our a request for recs outside of dark romance. I don't necessarily need it to be light and fluffy—a healthy dose of angst/trauma/etc. is totally fine, but I'm just not a fan of mafia, assassin, or morally gray type vibes.

Some books I've read with this vibe that I like include the MM books from Cambria Hebert's Westbrook Elite series and Alessandra Hazard's Straight Guys series (though to be honest, some of her books teeter on the edge of too dark for me).

I'm open to pretty much anything except for shifter books (non-shifter omegaverse is fine) or hardcore BDSM. Thank you!
