The first OST for EXO Kai's upcoming web drama, 'Choco Bank,' is now out!

The song to lead the string of sweet music for the series was sung by none other thanCLC, which lent their angelic voices to the bright and cheery track.  The song, entitled "Heartbeating Love," is very uplifting, the perfect song to accompany youths' budding romance.

Listen above! It's really cute!
