The actor appeared in the SBS variety show "Strong Heart" that aired on December 17th.
In the show a picture was shown, where Yoon Si Yoon is walking hand-in-hand in the red carpet with Park Shin Hye, and he is looking down, as the actress is wearing a low-cut dress, that is exposing her chest area, it appears as if he's looking down her chest.
He said " Park Shin Hye's dress was too long and her shoes kept getting tangle with the dress. I was actually looking at her feet. But she will explain it better."
Park Shin Hye continues, "The fringe of my dress tore, and my heel kept getting stuck in it. If you look closely he was looking at my feet."
Both Yoon Shi Yoon and Park Shin Hye will appear as a couple in upcoming tvN's drama "Flower Boy Next Door" starting January 7th.
