Criticism and controversy
The drama was accused of plagiarizing Japanese television drama 1 Litre of Tears. The name "Aya" was replaced with "Nayla", and the name "Asō" replaced by "Moses". Until now, there has still been no resolution nor any effort to enforce copyright law for this case.

The accusation that this series plagiarizes 1 Litre of Tears was accepted by the main actor, during an interview with Bintang Indonesia. "I don't want the viewers to compare me with the role on the real story. Especially when I am the main actor. Consequently, I will never want to watch the original. I'm afraid that I am being looked as imitating it. I want to be known as Chelsea. I don't care, let only the story plagiarizes, but the acting does not."

The series itself did not include any note that the show was "inspired by" or "adapted from" another, instead claiming that the story was merely a fiction.
