On her Instagram post, the phrase from the director-writer essay book, "I am your pet" catches the interests of the netizens, where she says, "I lived hard, but I only had the injustice. I lived hard; I wanted to turn back the time. I lived hard, and there was nothing."

Ku's post left her followers and netizens' mind with the question if this is connected with her current life which became hard after experiencing the crisis between her ex-husband.

But after a while, Ku Hye Sun posted her selfie with a caption "Melancholy" while sticking his tongue out.

She also gave more hints about her struggles, after posting the lyrics of her soundtrack, "Must I Die?"

In this regards, the viewer's views and opinions were divided into two. Some were saying that it is okay to let the actress do her own way on coping up with her current situation while the other side were saying that Ku Hye Sun only wants attention and find her strange for exposing too much private information publicly.

Ku Hye Sun, has been constantly on the topmost viewed and reacted topics as well as the most search in Naver, a Korean news and entertainment website since last month, the second week of August.

This is due to the issue of her marriage divorce with the Actor Ahn Jae Hyun. Ku has been active on her social media account ever since where she revealed the divorce statement as well as post updates regarding their break-up. Their divorce becomes hot on the public eye.

Furthermore, Ku also shares their full conversation of Ahn Jae Hyun as well as pressed the actor that the reason for their break up is the man's fault, where third party and different names of women were involved.

Though, Actor Ahn Jae Hyun who is timid on giving information about this issue spoke through his attorney where he filed a lawsuit against Ku Hye Sun for spreading malicious and false facts.

On the other hand, Ku Hye Sun temporarily retired in the acting field and is currently focusing on her career as a writer, director, and songwriter.
