Dong Suh Food Co. has released a new CF for their iced tea brand "TiO", which features JYJ's Yoochun! Yoochun plays the role of a high school teacher in the CF, and can be seen making a call to his mother, whining, "Kids these days are so scary. I want to transfer schools. Mom, you graduated from an all-girls high school, right?" Another teacher eventually catches him complaining on the phone and asks him whether he's going to quit school or not. Hilariously, Yoochun immediately puts his tail between his legs and exclaims, "No, I really like this school!" Netizens commented, "I'm really glad to be able to see him on public broadcast now", and "It'd be really fun to go to school with teachers like this!" Check it out below! Source: TV Daily Tip: Cindy
