Usually actors at the beginning of their career, do not have much choices, so they accept what they're given. Like Kim was gonna work with Broadcast Thai, but the Ch3 switched her around. But actors that have been around for years like Anne, Ken, Andrew, Tik, etc. can choose whatever they want. Right now for Kim is not at the stage yet to pick and choose. So she accepts whatever she's given or what Ch3 choose.
As long as Kim gets work with different productions it's good. I don't think she has to be a favorite to get good scripts. Look at James Ma, he isn't a favorite in a production yet. And when he was working with Nok, people thought James wouldn't get love scenes with Mint since M Team was Nok's bias at the time. But nevertheless it turned out the opposite. TV Scene love James, but is he a favorite of theirs? I'm not sure. As for Anne? She seems to like him, and she casted him in a good lakorn with a talented actress like Kim. So as long as the producer is professional, there's nothing to worry about.
Just keep Kim away from bad productions like Makers, UMA, etc. Lol.
