During this week's recording of KBS2's "Happy Together Season 3", f(x)'s Sulli confessed about a time when she was disappointed in TVXQ's Yunho. When MC Yoo Jae Suk asked Sulli if there was anyone out of the guests who were awkward to be around, she answered Yunho, and said, "Yunho always greets the other f(x) members kindly by saying things like, 'Our cute Luna, hello! Charming Krystal, hello!', but to me he just says, 'Sulli, hi', which makes me a little disappointed." Yunho explained, "Out of the f(x) members, I've known Sulli the longest and always thought I talked the most with her, so I didn't know Sulli thought things like that." Onew then went on to improvise a three-second time of reconciliation for just the two, making the studio crack up in laughter. The full episode will be broadcast on February 10th, and it will feature other SM Entertainment stars such as SHINee's Onew, TVXQ's Changmin, and f(x)'s Krystal and Luna.
