彼岸花开花叶不相识

This username draws from a type of Chinese flower named the Red Spider Lily. It blooms once a year but its flowers and leaves never appear together, symbolizing separation and missing each other. Users often use this to convey loneliness or the sadness in longing for someone they can't be with.
