EXO's Chanyeol and actor Seo Kang Joon held a piano battle.

In a recent recording of SBS' "Roommate", a 'pride battle' was carried out to see who would have to wash the dirty dishes.

Seo Kang Joon first stood up and announced, "I think I play the piano the best here," and proceeded to perform Yiruma's "Indigo" on the piano. Lee Dong Wook spotted Nana looking captivated by his piano skills, and said, "You look like someone who just fell in love."

Seo Kang Jun also performed EXO's "Growl", calling Chanyeol to the stage. Chanyeol seemed tense for a moment, but that dissipated when he performed Yiruma's "May Be" perfectly, which led to applause. The crew revealed that this rivalry flow became the center of attention.

Park Min Woo, who'd been watching in awe, said, "What am I good at?" eliciting a sense of sympathy from the onlookers.

This episode of "Roommate" will air on the 11th.
