In the recent episode of the KBS variety show ‘2 Days & 1 Night’, the cast had to correctly answer questions to earn their dinner dishes in Yeoju. One of the questions asked when Moon Se Yoon's birthday is, and four out of six members had to answer correctly.

Each member provided their responses separately in a room. Dindin and Jo Se Ho guessed October, Kim Jong Min mentioned November, Yoo Seon Ho thought it was July, and Lee Joon said June. Unfortunately, none of them got it right, causing disappointment to Moon Se Yoon, whose birthday is actually in May.
