The two main characters of SBS drama "I Hear Your Voice" Lee Bo Young and Lee Jong Suk revealed a cute picture of themselves wearing school uniform. The picture preview brought more excitement to those waiting for the first airing of the drama.

On June 2, Lee Jong Suk posted on his Me2day, "My sister is pretty, right? 3 days left until first airing!! Here we come!!!" along with a picture taken with Lee Bo Young standing shoulder to shoulder.

Then, yesterday, he posted up another picture, "What's your name~ What's your number~ Haha this is a secret because Sang Hyun might get mad that we took a picture without him... Don't we look good together? ^^," arousing jealousy.

Internet users who saw this commented, "2 days left now! I'm so excited," "Can't wait!," and "You two look so close!"
