Life as a Wind Tamer is not unlike being an ordinary human for Taeyang.  He has little trouble in hiding what he is the majority of the time, keeping the tell tale signs out of the open, but when he feels another of his kind nearby and slips up, it leads him into a fair bit of trouble with the possibility of a better ending than he could have ever dreamed.

Even a perfect love lasts only so long, for whatever reason.  But that doesn't mean there can't be another after the first.  Hyoyeon finds the love of her life, but when she loses him, it's not the end of the world.  There is light after the storm after all.
