Finally finished watching the 2005 version of "Neung Nai Suang" starring the legendary Ken Theeradeth and Janie Tienphosuwan. It`s my first time also watching Janie on-screen and she did a remarkable job as the stubborn Hathairat who never surrenders to Ken`s character Neung, a man who once as a boy bullied her.It has of course the same plot as the 2015 version, but only has less love-scenes and crazy drama (especially with the antagonists). But it has its charm to it despite being an old drama, and with Ken`s youthful handsome looks, he is the original Neung- and does a damn good job at playing him too. Some of the actors from the newer version even has their roles in this one too (one example is the actor that plays Neung`s father) which was very interesting. There is the chemistry between Hathairat and Neung that wins over it all, and the title does it well with staying true to the plot.A story about enemies turning to lovers, "One in my heart" depicting the way both of them irresistibly fall in love with each other-while staying at war against each other!
