Kai doesn't smirk. He just doesn't. And when you place this unsmirkable "shy" guy with a crazy rebel that has an ulzzang face, well, things can get pretty shmaq. Yeah, shmaq is a word the "crazy rebel" called Dae Hee Soo came up with 'cos she thinks she's the and some sort of hipster. 

And placing the shmaqalackin hipster with Mr. Idon'tsmirk is spontaneously setting the two innocent sweet angel puppies up in an arranged marraige. 

No, if you're wondering, the marriage wasn't set up for some cheesy buisness plan. You see, Dae-Dae-Duck's daddy placed rebel-chan in a newspaper ad for arranged marraiges. Shy fly guy's appa saw the ad and immediately accepted, to avoid the proposal Kai was about to give to his three years bad influence of a girlfriend. Pro. Po. Sal. 

Turns out Kai isn't the timid peasant Dae ends up thinking he is. He might not smirk, but he does sneer.

And our human lion of an about-to-get-married girl? She's got some pretty shmaq secrets, too.
