Soloist IU expressed her gratitude towards actor Lee Hyun Woo's mother.

On the January 13th broadcast of SBS's 'Inkigayo', MCs IU, Kwanghee, and Lee Hyun Woo began discussing about how they each take care of their skin during the winter.

IU asked, "When you're exercising outdoors during the winter, it can damage your skin, so how do each of you take care of your skin?"

Kwanghee simply answered, "Mist", whereas Lee Hyun Woo replied, "I've been frequently drinking citron tea. They say it's very good for your skin because it has a lot of vitamin C in it."

To this, IU revealed, "Actually, Lee Hyun Woo's mother brings us citron tea during 'Inkigayo' recording every week. Kwanghee and I have been drinking it well. We're very thankful," expressing gratitude towards his mother.
