I feel sorry for the other actresses who don't get promoted enough, but...Chompoo isn't the only one getting a lot of roles this year. There's also Yaya and Nadech- Yaya especially, has about 4 or 5 lakorns lined up and she's even 10 years younger than Chom. I'm not complaining about that since I like her; only pointing out that Chom isn't the only one getting a lot of work. I also noticed that Pong Nawat has been doing one lakorn after another for Channel 5(?); it seems natural that when an actor or actress gets popular or has a following, the studios try to make the most of them while they're still young.
I'm also not sure Chompoo will be able to film all 5 - that sounds like work overkill and not possible in just a year's time. It's possible she'll back out and that the casting isn't final for some of these lakorns. When Chom gets too old she'll probably not get that many offers anymore (sad fact of life), that's why she's making the most of her career while she still can and has her looks.
