On August 28, Koo Hye Sun shared a screenshot on her Instagram of her recently-published novel 'Heart-shaped Tears' (literal translation) ranking #67 on an online bookstore's bestsellers list.

Koo Hye Sun later posted another screenshot of the book hitting #1 spot on the E-book bestsellers list and wrote, "No.1."

The novel became a hot topic as Koo Hye Sun revealed that she had included some of her own dating experiences.

According to the report, sections that mention her husband actor Ahn Jae Hyeon will most likely be removed, as they are currently bickering over their marriage and divorce.
