The General's Reluctant Bride Ep. 9

Sunny, a modern doctor, is thrust into the ancient realm of Logopolis and bound to a merciless "childbearing system." Tasked with giving an heir to the powerful but heirless General Julian, she wins his trust and bears his child, only to discover the cruel twist: it doesn’t count unless Julian chooses her willingly, as both partner and mother of his future heirs.
