I have watched the Korean, Japanese and Thai adaptations of this drama and I must say, this was by far the BEST. In the other adaptations, the male lead had little to no character development. He treated the female lead with the same indifference as before they were married, however, with this adaptation, we see exactly when and how the male lead fell in love with the female lead. We see where he was, for lack of a better word, grateful for her love. In the other adaptations, there was no point in time where the male lead didn't feel entitled to the female lead's love. However, with this version, we can see where the male lead's character slowly changed. He smiled more, they laughed together, he paid a lot of attention to the female lead and there was a lot of skin-ship. I don't mean kisses or sex scenes, but occasions where they hugged, cuddled or spooned in bed. The male lead laughed with his wife, and although very few, he told her how he felt about her and that he loved her. Even when the family is together, there are moments where they laugh and make fun of each other- just like any other family. In the other adaptations, this wasn't the case. I'm not known to be emotional and I cried at more than one points in this drama.
The male lead showed his vulnerability when he thought of loosing the female lead. In this adaptation, the amount of love or interest that was given by the male and female leads to their relationship wasn't so unequal. Sure, the female lead put in more, but we cane see where the male lead is putting in some effort. Yes, the female lead was practically obsessed with the male lead, but there was practically no point where I felt frustrated with the male lead's attitude towards the female lead. I think for most persons who have watched the other adaptations, we all wished there was a time when the female lead left the male lead and he had to beg for her attention... well... we actually get a little of that. This drama has joined my list of favourite Asian dramas. I will definitely be watching this again in the future.
