uke is in a royal family but he's omega (lowest one too) so he's been set to marry a greenest alpha king in a greenest land where they treat omegas nicely (this author works never disappointed)
TYSM ALL OF THESE WERE SO GOOD
NO PROBLEM AT ALL !!
I'm looking for an omegaverse bl that isn't toxic and is a manga (I don't feel like reading a manhwa rn (●'◡'●)ﾉ )
