Mundanefan's manga / #child(4)

A story about an omega who takes advantage of the alpha while he is in a rut and has sex, then disappears. 5 years later they reunite, now the omega has a child. I dunno... it was longwinded and boring, not really my style to be honest. Felt like a bad shounen ai....

An omega with a child has to pay back a debt that his so called "fated pair" has taken. The yakuza alpha starts liking him and starts taking care of him, they eventually pair and the omega gives birth to his child as well.

An alpha who wants to be an omega, disguises himself as an omega and has a side job as a prostitute (?). He gets together with an alpha, and tells him that he is an alpha and that he can come inside of him, the next day the alpha top leaves. The alpha bottom leaves his work, and 3 years later he finally finds the top, and confronts him. He has given birth to his child and wants him to take responsibility for the child. The top has been looking for the bottom for these past 3 years, however he didn't his name, but only the fake one that he went with in the sexual services.
