Younghee Mandlebom was Leonard's nemesis that was from Korea and Leslie's best friend. She was usually mean to Leonard. But she actually cared for him, even showing that she had a crush on him at least twice. She doesn't want anything bad to happen to Leonard and does not appreciate it when he does something dangerous, scary, or foolish. However, even though she and Leslie were best friends, Younghee was secretly envious of Leslie's money and pretty looks like all the other kids (except Leonard).
Younghee was Leslie's best friend and Leonard's nemesis. She was in Leonard's class and like all the other kids, she was always mean to Leonard and insulted and beat him up on a daily basis. But, most of the time she cared for him and had a crush on him. She and Leslie were always seen hanging out and in fact, they both had romantic feelings for Leonard.
- She is similar to Helga G. Pataki from Hey Arnold! They both bully the main character but secretly have a crush on them.
