First, Rin appears to be a plain jane vis-a-vis Kronkaew's Miss Siam, Second Palad Saran seems to be a rough, action guy compared to Puttipat's Nerdy "Khunchai"-ness. (Based on the Padiwarada BTS pics, it appears that Palad Saran has scenes where he's poor and mopping floors in temples, etc.). Third, Palad seems to be more aggressive and inclined to hop on bed and harass Rin vs Puttipat who only stares stares stares. Fourth, Palad and Mint's character (still don't know what her name's supposed to be) are ex-lovers, meaning Palad should have had some affection for her in the past, whereas Puttipat hated Marathee ever since. I think Mint's character would be way more complex and would have a different impact in the story compared to the stock character portrayed by Marathee. and Lastly and most importantly, it appears that Palad and Rin in Padiwarada, as the title suggests, would get married at the beginning of the plot rather than at the end of the plot compared to Puttipat. So they would have to go through the whole husband-wife dynamic and pretend to be a good couple vs in Puttipat where Chai Pat and Kaew got married secretly and had to hide that fact from everyone except the villain. Stated otherwise, in Padiwarada, Rin is an "unwilling wife" and Palad doesn't particularly want her to be his wife, but eventually they learn to love each other. in Puttipat, Kronkaew is a wife, and Chai Pat wants her for his wife, and she also secretly wants to be his wife, but she's just stopping her self because of her pride/fear of "others", etc. I'm hoping with this difference, I get to see more of Bella's acting, i.e. "slowly falling in love" with the male lead which was really lacking in Puttipat.
