On her Instagram posts, Gu Hye Sun greeted her fans and followers saying,

" Hello, I am Ku Hye Sun.

I am going to say hello to you before I publish an essay book, "I am your Pet"

She then continued,

"Thank you very much for your interest and love, I was able to achieve my dream. I wish you good health and happiness. I love you."

The post also had an image attached which is a photo of her smiling along with her dogs.

Fans were worried because of this meaningful message and it would be a shock for them given that these past few weeks, the actress-director had been busy managing her career, due to her movie "Mystery Pink" selection for a short film festival as well as the exportation in Indonesia of her novel book, "Tears are Heart-shaped."

The actress has been more active in her Instagram account updating her fans, following the recent divorce case with former husband Ahn Jae Hyun.

Going back to the actress posts, she also revealed the prologue of the upcoming essay book which says,

"'I don't know what love is and don't believe it. But the only thing I dared to say is I love you, love you, love you and all I can think is my pet. And I also promise you to be your pet. I promise to be with you till the end of your world. Although you may not be with my end, I promise to take care of you with my two feet every day when you return to the earth. I promise that this love will last forever."

Furthermore, in spite of Ku Hye Sun's busy schedule over her marriage and career, she still doesn't forget to be a helping hand. It was reported that she decided to donate 20 million won from the Jinsan Gallery-Koo Hye-sun Invitational to the Institution for Pets under Ku Hye Sun's name.

In addition, fans become emotional upon Gu Hye-sun writing the lyrics of the song ''I Loved You'' where it says "We would have been happy if I didn't say I love you at that time."
