Its worth of watching, you should give it a try. No complicated relationship, no betrayal, no irritating characters, no misunderstanding.
Lai and Fah are siblings. Their parents taught them well, they protect and support each other P Ben and P Tor used to be rivals in Huajai Sila, its kinda fun to watch them in another lakorn in different roles.
Lai - Akat: healthy, supportive relationship
Fah - Hiran: At first i dont like Fah, cause she forgets all things that Hiran and his dad did to her family and love Hiran. its weird to watch her sleeping with Hiran. But it turns out Hiran loves her too. He is just spoiled by his abusive, manuplative father. His character growth in the end is good (praiseworthy to Bright)
The idea of recruiting people who used to be in prison, give them another chance to comeback to normal life is good and touching.
