Although F.T. Island's Lee Hong Ki did not win Park Shin Hye's heart when they co-starred in the musical comedy "You're Beautiful," the two have remained friends.

In "You're Beautiful" he played A.N.JELL member Jeremy. He falls for Park Shin Hye's character and is confused about his feelings because he thinks her character is a boy. Although three members of A.N.JELL fall for her character, she winds up with the lead singer, played by Jang Geun Suk. Poor Jeremy was heartbroken and had to ride the bus for hours to hide his tears.

But in real life it is Lee Hong Ki that she has remained closest to.

During the six years that they have known each other they have publicly displayed their friendship and affection for each other at least six times. Here's a timeline of occasions in which they publicized their friendship.

The caption read: I came to your concert! I thought you'd be mad at me if I didn't."

Although he is making a face as if he is really angry, she is smiling. Who could really be angry at such a loyal friend?
