Your synopsis is right Mahalo. What a coincidence that a few days ago, I was going through all my old VHS tapes and stumbled upon the original lakorn version with Saranyu, Nok Sinjai and Preeyanuch and was thinking when are the elders going to finalize this remake? DaraVDO announced their intention of remaking it 3-4 years ago where Kob and Nune were linked to it at that time. Kob said that she feels the need to be selective because she is also a mother and doesn't want to to portray any characters that wouldn't be suitable for her own kids to watch which is understandable. Even if she wanted to challenge herself with a non-prim and proper role, her mother in law would be the first to protest lol. I've never cared about lakorns involving cheating husbands but the older version was good because Saranyu and Preeynauch had really good chemistry. You could feel the sexual tension between them and Preeyanuch as always gave a phenomenal performance. She has that way of exuding so much elegance on screen.
As for Channel 7 being agitated over their former actresses, I can only understand Mai Davika's case. Her fans like to defend her saying that she has the right to move and gain more experience elsewhere and no one is faulting her with wanting to expand her wings. The problem relies on the fact that she was disloyal to Channel 7. Even before Nang Chada finished wrapping up, she was offered 5-6 lakorns, 3 of them were with Porshe yet both Mai and her manager rejected all of them. They were more focused on filling Mai's queues with events because that gains them fast money in greater quantities. Aside from that one charity event, Mai has never bothered to attend or take part in any Channel 7 concerts or events. Whenever being interviewed, she never really bothered to sincerely thank the elders unless the reporters say that she's the #1 nang aek aside from Aum Patchrapa. She would always say, if the elders really see me that way then I'm very thankful lol. She didn't even bother to wish Channel 7 a HBD but she congratulated GTH, claiming that they're like a part of her family. That's like a stab in the heart for Channel 7 elders who all adored her and promoted her over their other actresses. Aside from Min Pechaya and maybe Pookook and Bow Maylada, Mai doesn't have that much competition within Channel 7 so it's not like they neglected her or treated her poorly. She had her own spot that no one could touch. Even in her earlier days when she had those scandals like leaked kissing pictures with a supporting actor, with Dome, Mario, Guzjung, Channel 7 still had her back and gave her work and allowed her the freedom to only do one lakorn so she can open up her shop and accept all those magazines and events. No matter which way you look at it, Mai is seen as an ungrateful child. This is not the first time she's shown a lack of gratitude towards those who have done so much for her as evident in her case with former manager A Supachai. I don't think she cares what people see of her. Her real passion has always been with modelling and events so being a freelance gives her the flexibility and time for the other things she wants so even if she doesn't get stable workload in terms of lakorns, it wouldn't matter to her. In the back of my mind, I think Mai has always been a little bitter because she originally wanted to debut with Channel 3 but back then, A Supachai sent Nadech and Mark to Channel 7 and wanted to save Mai for Channel 3. However, Khun Daeng only wanted them to be evening praeks so A brought them to Channel 3 and switched Mai to Channel 7 in order to remain on good terms with Khun Daeng for future purposes.
