Real bad move on Ken's part, if it is him, ch3 has done so much for him and pushed him so hard, at least wait for your contract to expire before making moves like this. It just makes everything unnecessarily messy for him and create bad blood with people who are still his boss and can pretty much sink his career if he makes them mad enough. Especially so considering that I notice the Thais putting a lot of emphasis on gratefulness, and what he's done can be seen as the opposite of that.
I've always been meh about Ken, he just has no presence, whether as a celeb or as an actor. On a completely superficial note, I find myself really distracted by his teeth, I don't know if he had veneers work done or not, but it's all I can stare at whenever he shows up onscreen.
