Here's why:
* "Je" means "I"
* "Vous" means "you" (formal)
* "Vouloir" means "to want"
The correct phrase would be:
* "Je vous veux" which translates to "I want you" (in a romantic sense).
However, this phrase is very strong and direct, and it's important to consider the context and relationship before using it.
If you're looking for a more polite way to express wanting something from someone, you could say:
* "Je voudrais..." which means "I would like..."
For example, you could say:
* "Je voudrais un café, s'il vous plaît." (I would like a coffee, please).
