이번 주는 정말 바빠서 노무 너무 피곤해요. ㅠ_ㅠ
Everything else is good! People also say "너무" 바빠서 because "너무" has a negative connotation as in "too". For example,
너무 매워요. (It's too spicy.)
너무 추워요. (It's too cold.)
너무 뜨거워요. (It's too hot.)
But you can also use it for something positive like "너무 예뻐요!" "너무 귀여워요!" to really emphasize that feeling :) So it's kind of like, "It's damn pretty/cute!"
Hope that helped!
