In-law Zoned

The Friendzone, but worse. When someone you like would rather want your kid and their kid to get married.

Person 1: I like you.
Person 2: Sorry I don't see you like that.

(Decades later)
(Person 2 marries Person 3)
(Person 1 marries Person 4)

Person 2: Wow I hope our kids get married.
Person 1: (Bruh I just got In-law Zoned )
