On October 1, EXO-CBX consisting of members Chen, Baekhyun, and Xiumin, performed at 'Fandom School 2017 Korea Music Festival' which was held at the Gocheok Sky Dome.

The trio performed tracks "The One" and "Hey Mama" as the audience was blown away by their powerful choreography.

During the last part of "The One", Baekhyun took the time to send out a romantic heart pose to his dear fans when a sudden firework explosion startled the idol.

Embarrassed by the unexpected fireworks, Baekhyun couldn't help but smile as he looked quite alarmed putting his hand over his chest. Chen meanwhile was unfazed and had a big smile on his face the whole time.

Seeing this, netizens commented, "How cute," "Is it possible to be this adorable?"

Now that's a priceless expression. Watch the cute incident below!
