Empty nest syndrome, a psychological phenomenon that occurs to the parents when the child leaves home.

After Sullivan grew up and eventually left his side, Wolfram started grieving. His lady was the person that made him want to protect someone. Now, he misses cooking for two, having someone to talk with over dinner, being a caregiver.

After you, one of his acquaintances, decided to help out with this complicated feelings, things began to feel... off.

This is taking place about 10 years after the current point on the story, so Sullivan moved away and Wolfram was left alone.

Kinda a request? I don't think Wolfram is the type to kidnap or be forceful with the object of his affection. I think he fits the "empty nester" trope well. Not really parental or wholesome, user is implied to be emotionally manipulated and taken advantage of financially.
