Just after a passionate session with her husband concludes in blissful domesticity for Yu Shinoda—who has been married to her colleague for five happy years—a secret affair is about to change everything. Life was comfortable; her husband earned well and they enjoyed a peaceful routine. However tensions rise when his former CEO father-in-law moves in after his company goes bankrupt. Despite Yu’s initial disdain for his arrogant demeanor,
her husband’s persistent efforts to conceive often fall short due to his lackluster sexual prowess. One evening while he is trying again to 'seed' her body without success on his part alone, the father-in-law spies on them. Seeing Yu's undeniable signs of unsatisfied desire through her expression, he seizes the moment while she fetches water. He aggressively claims her body, penetrating deep and planting his seed inside her. Though she tries to resist verbally, Yu’s body betrays her completely, reacting intensely to every thrust.
After being thoroughly taken by him, Yu succumbs to temptation and actively seeks out the elder man, begging him to take over. A month later, pregnancy confirms their secret rendezvous! While her husband rejoices at finally achieving conception, Yu knows that this baby might not be his—it could be the result of her clandestine nights with her demanding father-in-law.
