On March 17, Koo Hye Sun took her personal social media and shared an old poster of her drama 'Boys Over Flowers' (2009).
In the caption, Koo Hye Sun wrote, "The unnie who used to fill my hands with hand warmers. The unnie that I regret I don't have a single photo with. Rest peacefully in heaven, beautiful person."
While Koo Hye Sun played the female lead 'Geum Jan-di', Jang Ja Yeon played one of the three "mean girls" named 'Sunny'.
At the time, the investigation into her death did not unveil the names in her letter, and only indicted her agency CEO and her manager.
