Help needed

First: Omegaverse; yaoi. It's about beta loving omega but omega will get marked from alpha but in the end omega will stay with beta because he loves him but he can't have sex 'cause of the mark (he vomits I think) in the very end they have a baby (beta and omega).

Second: marked omega - isn't with his paired alpha. The new guy is trying make a new mark over the first (maybe it's the same manga like the first one. Not sure.)

Thank you! I will love you if you will help me.
