With his stage comeback on the horizon, Rain has been working even harder than usual to make his long-awaited return worth the wait!

In a photo shared by Cube Entertainment, Rain is shown with his abs on full display, working on a piece of choreography with a baseball cap turned on his head.

Returning with his newest album 'Rain Effect', Rain is scheduled to begin the rounds on the music shows this week. Hopefully all of his hard work pays off!
