Sooo-jin posted on his 22nd instagram "Play 'Understudy! Two hours of tight trio".
"Everyone is really good, and the more I think about it, the more fun it is. It was better to be with Yeon-hee who cried and laughed together until recently."
The photos released together showed So Yoo-jin and Lee Yeon-hee smiling together and sharing their leisure time.
Meanwhile, the two have recently joined the stage of Play 'Lear King'.
