What is Lee Jong Suk's biggest problem with having to act in a school uniform?

The young actor had to wear a high school uniform for his role on 'School 2013' as well as his latest drama 'I Hear Your Voice', and he was asked about how he felt in uniform on 'One Night of TV Entertainment'. He said, "I'm in my mid-twenties, so I have a problem. I have to shave 2-3 times a day because I'm in a school uniform. My facial hair grows pretty fast, so I have to take care of it every time I get in a school uniform."

On having jumped up 950 places in online search results after 'School 2013', he said, "For me to feel a difference, I have to go out, but I never went out because I was busy from my dramas. Before, I'd search my name when I thought I did a good job acting, but I wouldn't rank up in search terms. But once when I talked to Kwanghee on the phone on a variety show, I ranked high."
