Kim Taeyeon and Leeteuk Park have been together since the year of 2009. As soon as Leeteuk met Taeyeon on stage, he immediately fell in love. From that moment on, he started to stalk her. Everyday. Every free time that he has, he would dress up as a normal guy, and where ever Taeyeon goes, he's there.

But what if Taeyeon didn't dislike that fact, and turns out to like Leeteuk as well? The only answer to that is their secret wedding 8 months later.
