140702 Girls Generation Tiffany reveals Sunny's drinking habits on MBC FM4U's "FM Date" Radio

On the July 2nd broadcast of MBC's  'FM Date', Sunny had Tiffany, on as a special guest.

She said, "Sunny is different depending on whether we are out for a meal as a group or drinking at home.  Sunny drinks with great self control and mental strength.  One day, we were drinking comfortably at our house and she got drunk, but I could not tell she was drunk.  She is a pro at the poker face."

She continued, "While we were drinking, Sunny says she would go in for a bit and come back later, but she does not return for a long time.  When that happens, she is sleeping very prettily."

Sunny added, "I'm sleeping like Snow White."
