BraveAppointment1:
Earth the actor is a helluva good looking man. He's also a lot nicer / more relatable than Phu the character, who is older and has that hard "stern" look about him. In interviews, Earth laughs a lot and has a real heart-warming vibe about him. He says he is "shy" (not sure what Thai word was used), but he sure doesn't come across that way.
Earth is a stunner in the looks department. He seems like a guy who's always good for a laugh and loves to tease, but he's also a very sensitive person. I don't know if you've ever seen the BTS clip where they were filming the counting Stars scene but Mix actually fainted in Earth's arms. At first, Earth though he was in character and improvising something but then he realised that Mix was actually out. As the crew rushed around MIx, Earth kind of got jostled to the side and you can see him sobbing into into the assistant director's shoulder.
Mix had more scenes than Earth did for filming but Earth would often go to the set to support his friend, Mix, anyway.
The Thai concepts of shyness and modesty are still difficult for me to pin down. They do seem to be shy about expressing certain emotions, at least publicly.
