The story was about twin sisters who had the same face but totally different personalities. FL had to pretend to be her sister who was a successful producer in the entertainment industry when the latter was heavily injured in a hit-and-run accident. ML had a crush on FL since they were young so he came up with schemes to force her to live under the same roof. FL was a normal damsel in distress and ML was a knight in shining armor who carried the burden of saving the FL every time she got into trouble. The plot twist here was that ML was not a typical kind-hearted hero who just wanted his beloved to be happy. He can be crafty in every possible way to win the girl's heart. However, he was fully devoted to her and his love for her was consistent throughout the series. I really enjoyed their love story. I did not take an interest in the supporting characters though and I skipped most parts because of the numerous evil love rivals of ML and FL. However, I was pleasantly surprised at my enjoyment of this drama until the last four episodes which aggravated me beyond endurance. I would have given an 8.5 rating to this if they had not focused on the FL's childhood friend in these episodes.

This is not the first time for me to watch Luo Zheng's drama but he seems to have captured my attention and admiration only in this drama. He is undeniably so handsome and he has the potential to become one of those A-list actors. He could portray his dark character very well and his eyes showed his deep love for the FL every time he looked at her. Some people may have the impression that his character is very creepy and manipulative to the point that he does not deserve to be in a serious relationship with FL. From my perspective, he rather gave the vibes of a manipulative boyfriend from time to time, especially during the times he discreetly attempted to get close to the FL. Despite that, I quite liked his shrewd and mysterious character. I could not help falling for him when he judiciously made careful plans to achieve his objectives in both his love life and business. In addition, I quite admired his unconditional love for the FL (though this kind of love would be quite controversial in reality.) Nevertheless, his obsession for her did not breed psychotic behaviors like harassing the girl when they have disputes or stalking her all the time and appearing out of nowhere whenever FL was distressed in the way that the second male leads in other Asian series do.

Suffice it to say that FL was the worst character here. Don't take it amiss just because I criticized her character strongly. I honestly love Rain Wang and her depiction of the characters but her main character was so poorly written that she looked like a 10-year-old girl. I understand that there can be not-so-smart FLs but her naivety and lack of reasoning skills to solve problems were too much. Even until the end, she was not able to deal with the crisis that was brought on by her childhood friend. Moreover, her career path was not expressed by the writer clearly either. The writer did FL character dirty in the entire series so badly. (I could not stand her dubbed voice as well. It was so irritating.)

This series was apparently made on a shoestring budget because there was no single decent OST song. However, I appreciate that they did not repeat an annoying melody throughout the whole series, which is an everyday thing in some low-budget series. On the other hand, ML and FL were lucky to have good designers for them since most of their clothes were suited for their roles and each scene in the series.
Overall, I would recommend "Nothing but You" to anyone who is into obsessive male leads and a cute love story with several sweet moments between the main couple. Plus, the chemistry of the main couple here was wonderful and very believable. However, if you cannot stomach annoyingly evil characters and naive FL, this drama may not be for you.
