2PM has released their dance practice for "Promise (I'll Be)"!
The boys filmed their dance practice not in a dance studio, but what looks like a theater. The empty seats and the dark lighting add to the mood of the entire performance. Of course, as usual 2PM there is a bit of shenanigans as Taecyeon can't stop smiling in the beginning of his part, but there's barely any as they keep the mood serious as much as they can.
