I actually enjoyed the old version and happy that Mint is taking this lakorn along with James Ma. My perspective of this lakorn is different from many views or at least this was how I remember from the old version.
1. Pra ek and Khun Ying love is more of admiration from childhood. He always thought she is the princess and he wants her, but the idol is not the right person. He thinks he loves her, jus like everyone think they love their first crush and because she tried to push him aside, it made him want her more, but that can't be considered of love.
2. I believe he slowly build a love feeling toward nang ek as he knows her more, but just didn't realize she is really the woman he loves. Because she is not his type, he didn't think he will love her. She is not just a friend to him, but she's everything he needs; when he's sad, he wants to be with her, when he's happy he wants to share the story with her; this is more of a love feeling. It was sad, they didn't show much when he realized he loves her. I hope in Mint and James version, they will extend this part more.
3. The other ladies, he never showed love interest in her (the sister). He always think she is a sister, which why he ran away when the mother tried to trick him to go into sleep with her. Thus she can't be consider as another woman of his.
4. The old lady like him, but he never showed any sign of love toward her either. He sees her as a friend's mother only.
I hope in this version, they give more screen times for the pra nangs and make pra ek realize his feeling earlier toward nang ek and have him knee down to ask her for her love. That will be perfect for Mint and James.
