IU herself had explained the concept behind "Zeze," the song on her new album which drew criticism from listeners, "'My Sweet Orange Tree's Zeze is a character with flaws. In a certain light, he is described as an 'angelic child' and a 'child with a shining heart,' but in another light, he is portrayed as 'a devilish, contrarian character.' He is innocent but also cruel. He is very mischievous so he acts meanly towards others. It makes sense because Zeze is a young child...that's why I feel he is charismatic and sexy. I think it's an immense charm for the character to have the reader be drawn to his two traits and cheer him on until the very end."
The netizen wrote, "Those who read 'My Sweet Orange Tree' will know that you can't describe the character like that. If you take what she said at face value, she's basically saying that a boy who was sexually abused is charismatic and sexy.
