South Korean TV star Yoo Joo-Eun died at the age of 27 on Monday.

Yoo's older brother Yu-Han shared an emotional note written by the actress before her death, where she revealed her desire to end her life, while telling her family, "Please don't cry."

He posted the letter on his sister's Instagram page. "Joo-eun left here and went to a comfortable place. If you have time, please say goodbye to Joo-eun on her way," he captioned the post.

"I'm sorry I left first. In particular, I'm most sorry about mom, dad, grandma and older brother. My heart is screaming that it doesn't want to live. Your daily life may be empty without me, but please live bravely. I'll be watching you all. Don't cry. You'll get sick," the actress said in her letter.

The "Joseon Survival Period" star added, "I'm not sad at all right now. [It's] very determined and calm. Maybe it's because I've been thinking about it for a long time. I've lived a very, very happy life. So that's enough for me. That's enough. So don't blame anyone and live without me."

She also said, "I really wanted to act. Maybe that was my everything and part of me. But it wasn't easy to live that life. I didn't want to do anything else. It was so hopeless. It's a blessing to want to do something, but I also realized it was a curse to only want to do one thing."

Yoo's brother has since made her Instagram page private after sharing her last note.

The actress made her acting debut in 2018 in "Big Forest," and also appeared in MBC Network's "Never Twice" drama.

Her brother did not mention how the actress died.

South Korea's singers share the same pressure as their counterparts in the film and TV industry.

Commonly known as "idols," K-pop stars are expected to maintain a "perfect" and "ideal" image for fans, which becomes a source of pressure for many of them. Aside from living a squeaky-clean image, they have to compete for attention from the public and ensure their records reach large sales.
