I think so because when the woman woke up, she didn't see the story book and guitar, because Zhe Xiu fulfilled his promise. Although he wanted the woman to stay, he didn't do that, because he wanted her to think it was just a dream and hope that she would go back and live a happy life. Because after washing for 47 years, Zhexiu loves someone not to let that person stay for himself, but to hope that she will be happy.

Plot introduction:
Sun Yi (Park BoYoung) is a frail woman who needs rest, so her mother and daughter moved from Seoul to a villa in the country. While cleaning the house, Shunyi accidentally discovers the wolf child (played by Song Joong Ki Song Joong Ki) left here by the mysterious former head of household, Dr. Park.
Shunyi's mother took in the boy who was still a wolf out of kindness and named him Zhexiu, so four people began to live under the same roof. At first, Shunyi didn't like the uninvited guest who couldn't speak, and wolfed down his meal. However, getting along with each other day and night gave Shunyi the idea of caring for and cultivating Zhe Xiu.
She began to teach him to eat, read, read, and play the guitar for wolf children. Zhexiu's enthusiastic concern for Shunyi is very useful, and he does what Professor Shunyi gives him seriously. Lonely Shunyi became happy because Zhexiu gradually merged into his own world, and he had a different kind of love for him.
However, this beauty is broken by the covetous Zhitai (played by Liu Yanxi Yoo Yeon-seok). He is bent on gathering and provoking many forces to kill Zhexiu. In order to protect Zhexiu, Shunyi had to face the reality of being separated from his relatives. ?
