Now, his foster father was the leader of the latest version's antagonist organization.He would expose his identity six years later, hesitate and then defect from the protagonist's side. Ultimately, because he decided to take a fatal strike meant for the player character, he was killed by his upright older brother in a transitional CG without even a chance to enter the main content.——But the problem was not too significant. Aiwass also knew many secret advancement routes exclusive to the player character, as well as the Nurturing Secret Sequel regulations of the various Paths.

Only to find herself staring at a positive pregnancy test a month later.Kate Woods, the supposedly ‘barren woman,’ was pregnant.The stranger had accomplished in one night what Matt could not in five years.Now that Henry has given her a choice, would Kate leave her deadbeat husband and jump into the sea of uncertainty with this young man?Or would she stay with Matt, her husband who cheated on her for the sake of their families?
