On November 7 episode of MBC's television show 'Point of Omniscient Interfere', Koo Hye Sun reminisced shooting KBS' hit drama 'Boys Over Flowers' in 2009.

Koo Hye Sun said, "It honestly wasn't easy at all. I remember having a concussion after jumping into a swimming pool with my head first."
The actress resumed, "But I had to continue shooting the scene despite my injury, because the drama couldn't be televised the following episode otherwise. I even fainted in the middle of shooting that I had to get an IV drip."

She went on, "We once went to New Caledonia to shoot. Out of the whole shooting of 'Boys Over Flowers', I would say this one was the hardest since I had no opportunity and time to view the beautiful ocean while there."

She said, "Oh, I was actually in a relationship then, but ended up breaking up with him in New Caledonia. We were filming on a small island, and I couldn't get any signal on my phone."
She added, "He couldn't reach me for like a week, and didn't believe that there was no service there. So, we just broke up like that."
