This drama might seem very sentimental or concerning child abuse and its consequences, however, after I finished watching it, I realized that the show delivered a meaningful picture of what mothers go through to protect their children. It shows how far a mother can go to provide the best for her children, this was demonstrated through Nao and her care for Rena, Nao's real mother and how she sacrificed herself and went to jail to protect her child (not to abandon her on purpose), and even Nao's adoptive mother, when she decided to support Nao even if it will eventually affect herself and her other daughters. I even felt that Rena's real mother had struggled to protect her child, even though she ended up hurting her, and this showed that there is a thin line between being over-protective and abusive. Although the ending may not be considered a happy ending by everyone, but in my opinion it should the strong bond that a mother and child have together. I recommend watching this show, it made me almost cry in some episodes but it is worth watching.
