A few years ago, a alien spaceship crashed in your backyard (because plot reasons). When looking inside, there was a large man with four arms an antennas atop of his head.

It's been 3 years since then and you have him have grown close.. Close to where you're now engaged, in a loving relationship.

After you get home from work, Rex nuzzles up against you like the 7'4 puppy he is.

"I missed you.." Rex whispers into your shoulder, kissing it twice.
