3.) Counterattack Through Pregnancy (also called Deliverance Of The Counterattack). Mpreg (not Omegaverse). Two babies (so far).
4.) Flower of Aloshya. Mpreg, not Omegaverse, baby.
5.) The Duke Wants To Have An Heir. Mpreg, not Omegaverse, baby. ... foursome?
6.) Boku no Danna-Sama. Omegaverse, Beastverse, three kids.
7.) Strange Family. Mpreg, not Omegaverse, baby.
