Informal:
* 너한테 화났어 (neo hante hwanasseo): This is the most common and direct way to say "I'm mad at you." It's used among friends or family members.
* 너 화났어 (neo hwanasseo): This is a slightly more casual way to say "I'm mad at you." It's usually used with someone you're close to.
Formal:
* 화가 났어요 (hwaga nasseo): This is a more polite way to say "I'm mad at you." It's used with people you don't know well or are older than you.
* 화가 나요 (hwaga nayo): This is a more formal way to say "I'm mad at you." It's usually used with someone you respect or are in a professional setting with.
Adding "at you":
You can add "at you" to the end of any of these phrases by adding "너한테 (neo hante)" or "당신에게 (dangsin ege)". However, this is not always necessary, especially in informal situations.
Example:
* 너한테 화났어! (neo hante hwanasseo!) - I'm mad at you! (informal)
* 화가 나요. (hwaga nayo.) - I'm mad. (formal)
Remember that the best way to express your anger depends on the situation and the person you're talking to.
