The All-Round Son-in-Law of the CEO

A wealthy family's live-in son-in-law joins the army and returns as a God of War. From then on, he becomes his goddess wife's personal bodyguard!

"You good-for-nothing, you couldn't even protect my daughter!"

"Well, anyone who messes with my wife gets sent to the afterlife, along with their whole family."

"You're a grown man. How come all you can do is live off a woman?"

"I'll give her ten billion, as long as she keeps serving me every day."
