The Broken Ring : This Marriage Will Fail Anyway
Rakka no Alpha Ou
There was no rape in this manga. A story about a prince falling in love with a cute kid and promising to come back for him when he’s older, however when he gets older he is hella tall and muscled up and an Alpha who bits the princes neck turning him into an omega.
Yankee Ω wa Kemono Ou-sama no Mono!
A delinquent gets sucked into another world through a mirror. He then ends up saving a guy who turns out to be an alpha and a royalty. The alpha tells him that he is his fated mate, turns out his body changed when he got sucked into this world and he became an omega. Long story short they live happily ever after. Felt like this story was milked.... Didn't like it. It could have been short but nope.
