Hani revealed she had her own 'Death Note' during her EXID days.

On the April 9th episode of 'Strong Heart VS', Hani shared that she wrote down all the unfair things that happened to her and her EXID members. She expressed, "When I debuted, the idol industry itself was less developed than it is now. At the time, there were many things that I felt were unfair. I recorded all the unfair things because I felt like I was not treated like a human being, but too much like a commodity."

Hani then revealed what she wrote, saying, "I wrote things like, 'The manager came into the house and took our cellphones,' and I went to find the person who the most powerful person at our label was scared of. It was an investor. I took all the members with me and told them everything."

Hani continued, "Since then, they could no longer make unreasonable demands of us. Since then, it's been called the 'Death Note."

On the same episode, Hani revealed what's changed about her body since her promotions with EXID.
