Liang is the youngest of a low-income family's seven children. Working at a fast food restaurant and a video store while attending Holy Angel University in his birthplace of Angeles, Pampanga, he paid his way through college. He earned a BS in Education with majors in physics, chemistry, and biology.

Liang started working part-time as a ramp model, until his manager discovered that Ronnie could sing and encouraged him to join singing contests. Among them was Pinoy Pop Superstar.

Liang then joined Pinoy Dream Academy and made it past the initial screening to be one of the 20 scholars to study inside the academy. After a few months, Ronnie made it to the Honor's List of Six and ended up as PDA's second runner-up.^{[citation needed]}

Liang now is being managed by Viva Artist Agency.
