The Ultimate Live-In Son-in-Law

I was reborn as a live-in son-in-law after a car accident. So what?

Should I be meek and submissive? Or grovel at everyone's feet?

No. Those words don't exist in my dictionary. There's only one saying:

"If you look down on me, I'll make sure you can never measure up to me!"
