Is there any omega x omega ?

Omega x Omega BL is really rare, I've seen omega tops but not a romance between two omegas

This is Omega x Omega (just beware their relationship is toxic and the story deal with heavy themes such as rape, sa and sexism and discrimination against omegas ) https://www.mangago.zone/read-manga/takatora_and_the_omegas/

Not quite what you’re looking for because it’s a 3P, but 2 of them are omegas.
