On the December 9 installment of JTBC's 'Knowing Brothers', Junho appeared as a guest alongside his 'Just Between Lovers' co-star Yoon Se Ah. The 2PM member revealed, "I was traumatized after hearing I looked like Rain while I was in high school," during his Q&A segment.

After the 'Knowing Brothers' crew tried to guess why, Junho explained, "In high school, a group of noonas found me and said, 'You don't look like Rain. You're completely ugly!'" Apparently, there were rumors at his high school of a student who had a resemblance to Rain, and the mean girls didn't think Junho lived up to his reputation.

He continued, "I was hurt. After that shock, I lived a very quiet school life."
