Na'ek could had find better ways to get back at na'rai. BUT...her main objective is to make Thita feel the pain of having a lover taken away from her, to make her fell what Roserin (na'ek cousin) felt when Thita took Woot away. So it's like giving Thita a taste of her own medicine.
Kompai's character is like Kongpope in Roy Leh Sanae Rai, where pra'ek married na'ek to get the money back (the money that his father gave to na'ek). When meeting her his main goal was to get her to marry him, at the same time fallen little by little in love with her, and only realizing his big mistake when seeing her heart broken and running away on the wedding day. Just like Kompai, using Panin, but at the same time falling for him, not realizing it until a big break (wedding day Panin confronts her).
Did anyone see the preview for episode 5. lol. There was a loud thump when Chakrit threw Kob onto the bed.
