Sistar's Hyorin revealed having a military-strict curfew growing up.

On June 24, Hyorin appeared as a guest on talk show 'Hello' which brings out non-celebrity citizens to share their personal struggles with the panel of guests for a time of discussion and resolution.

A 34-year-old man came on the show and made a complaint about his wife who insists that he come back home by 9 PM every day. He explained that due to the nature of Korean corporate world that involves frequent after-work drinking with higher-ups and bosses, her request is nearly impossible to follow.

Hyorin chimed in, revealing her strict curfew as a student.

"Because my dad was a marine officer, I had a hard curfew at 8 PM every day," said Hyorin.

She added, "I was deathly scared of my dad so I kept the curfew to the dot. But when I played, I played really hard."
