Watashi ga Yogen no Ko wo Umu made: Mio no Kekkon - Kizumono no Hanayome

"Mio is the one who will give birth to the hero the Kyogoku family has long desired. Therefore, whomever marries Mio will become the next head of the family." Mio, the daughter of the Kyogoku family, suffered a serious injury from bullying in her childhood and left her village. Five years later, when the beautifully grown Mio returns to her village, it is prophesied at the family meeting that she will give birth to a future "hero." At that moment, the young master of the main family, who had bullied Mio in the past, begins to force her into marriage. To escape marriage with the man she despises, the girl clings to a "loveless marriage" and "pregnancy" with her first love. [Official Japanese](https://shonen-sirius.com/c/yogennoko.html)
