Jo Kwon and Sunye have spent a lot of time with each other as trainees in JYP Entertainment and during a recent recording for Happy Together Season 3, the latter revealed a story where they spent nights at a subway station. Sunye revealed during the show that during their trainee days, they had to practise till very late into the night. And at times, they would miss the last bus back home. They would end up spending the night at the subway station until day arrived. Familiar story? Well, Jo Kwon mentioned about this earlier this year. Sunye also expressed something about Jo Kwon, "Jo Kwon's voice was very clear, resembling a female voice in the past. I never thought that his voice would change someday, so I never felt anything emotional for him at all." This episode with the Wonder Girls will air on June 10th.
