Sunny revealed that she has been to a public bath after her debut as SNSD.

In KBS 'Invincible Youth 2' aired on March 10, the stories of G8 members and the elders were shared through their 'dutiful spa trip'.

Before the trip was over, the MCs asked in the bus if anyone has been to a public bath. As girl groups are garnering much attention, it is not easy for them to go to such a public place.

Many members such as Suzy and Amber said they have never gone, but Sunny confidently answered "I've gone", surprising many.

Members asked, "How did you go when everyone's going to recognize you?", "You went with that hair color?", etc. When she was asked what people's reactions were like, she said "Wow!", bringing laughter to the set.
