On the 3rd day of the cast's trip to Okinawa, Japan, Yoonseo went on a date with rapper Hanhae, going for a stroll by the seaside. When Hanhae asked, "Are you happy right now?" the actress revealed, "Yes, I'm happy these days."
She continued, "About 3 months ago, I was really sick. I had a big surgery. I had my left lung removed. I almost died. Back then, I thought to myself, 'Everything is meaningless'... It was a rare form of illness, so there wasn't really a name for it. It was because a blood vessel near the lung grew defectively. I had it since birth, but didn't know about it... but now I'm all cured of it."
Yoonseo went on to explain how difficult it was not being able to do anything normal while suffering from her illness, and compared to then, she is happy about being healthy again.
Back in 2016, Yoonseo was cast in MBC drama 'Person Who Gives Happiness', but had to withdraw from the project due to health issues. Glad to hear she's doing well now!
