"Still Beautiful as Before, But My Heart Is Not What It Used to Be": This online name juxtaposes physical appearance, which remains unchanged over time, with inner feelings that have changed greatly. A person using this nickname may be trying to express that although they look the same on the outside, they've gone through some internal transformations or experienced pain in their heart.
