I'm positive he's moving, why else would he back out of the lakon called Lui and usually actors will come out to deny these types of allegations ASAP. Also, there hasn't been any news of future projects with CH 7. I'll be darned if he signed a contract with CH 3 the same time Mario did. There are so many leading actresses he looks good with at CH 3, CH 7 have too many young chinky looking ones.
He wasn't cast in Duay Rang Atitarn either when there were rumors early on he that was gonna be in it. Another point of interest that adds to my suspicions.
