2PM’s Taecyeon and MONSTA X’s Shownu delighted fans with an adorable exchange on Twitter!

On January 20, Taecyeon shared a fan-taken video of MONSTA X’s cover of 2PM’s “Heartbeat” on Twitter. The group covered the iconic hit as a special performance at KBS’s “Music Bank in Hong Kong” the night before.

Taecyeon, who is currently serving in the military, wrote in the caption, “So cool. You must have worked hard.” He jokingly added, “If our junior artists keep tearing up the stage like this, will I be forced to do the same during our comeback tour? Hehehe.”

Shortly afterwards, Shownu expressed his gratitude by responding on Twitter, “Thank you for looking kindly upon [our performance]. Please keep watching us a lot in the future, hyung, hehe.”

“Music Bank in Hong Kong,” including MONSTA X’s cover of “Heartbeat,” will air on KBS at a later date.
