Girls' Generation guested on KBS' "Yoo Hee Yeol's Sketchbook" on March 14th.

During the show, there was a segment in which Yoo Hee Yeol asked the girls some of the questions about love and dating. When it was Yoona's turn, he asked,"If there's a senior that you have known for a long time and he keeps being half joke half serious and saying that you are his ideal type, then do you think he likes you?"

After listening to the question, all the members and also the audience immediately burst into laughter and gave out a loud cheer for her, but instead of saying anything, Yoona just shyly turned on the green lighstick and put it in front of her face to indicate it as a "Yes" answer.

Seeing how happy she was at the indirect mention of her boyfriend, it seems they are still dating well with each other.
