Any one else watch Sungkyunkwan Scandal? I finished it last week. 

That would be the easiest couple to ship--ever. Song Joon Ki's character couldn't be more flamboyantly gay. Yoo Ah In's character's half-hearted refusals to Joon Ki's advances are adorable and flirtatious. Seems he finally gives in at the end of the series, too. 

I imagine the two of them live together and often with their married professor couple friends for double dates.
