Before I recommend you a few, what are you looking to not be recommended? Any content warnings you'd like to not find in your stories? I've read a few omegaverse stories that I think are not as popular as others do hopefully I can recommend you something new. (For example, I know Unromantic is super popular -with good reason, but not one id rec since you said you've read a lot!)
Are you amenable to short/~5 chapter long stories?
‘Kiraide Isasete’ is a personal favorite of mine, healthy relationship between the mc and ml, kids, and overall really sweet. (TW: topics of sa) (the sa wasn’t don’t by the ml btw)
‘Kiraide Isasete Asanaga-sensei to Yanagi-sensei’ is a spin-off of ‘Kiraide Isasete’ and it’s the story about 2 side character in the main storyline getting together and falling in love (I don’t remember there being any triggers, but I haven’t read it in a bit sorry)
‘Shima-chan Chi no Tsugai Jijou’, is another cute one 2 dads telling their daughter how they fell in love. (I don’t know about TW I haven’t read it in a bit)
‘Unromantic’ is another personal favorite of mine, the seme is a golden retriever bf and the uke is a black cat bf. Set in a universe where Omegas are looked highly upon, this is about 2 men falling in love but having to deal with one of their families getting in the way. (TW: Dubious Consent)
I hope this list helped and you like any of these on here! :]
I feel like I’ve read all the omegaverses out there that have multiple chapters to them. Like I’ve read love is an illusion and all the overrated ones but I need new ones plzz help!
