Tickets for Yoon Ji Sung's upcoming performances of musical 'Those Days' have completely sold out.

On January 8, 'Those Days' opened their second round of ticketing. Different from the first round, the tickets sold at the second round were specifically for five nights where the Wanna One member was going to be starring in the musical, and according to the press, these tickets sold out in a surprising five minutes.

Meanwhile, 'Those Days' is a musical written around the songs of the late singer-songwriter Kim Kwang Seok. Yoon Ji Sung will be starring as a character named 'Mu Yeong', a witty and free-spirited former guard for South Korea's Cheong Wa Dae. This will be among the idol's final activities before enlisting in the military later this year.

Yoon Ji Sung's first performance will be held on March 5.
