Nelly - Dilemma ft. Kelly Rowland no matter + 疑問詞

No matter what I do
All I think about is you
Even when I’m with my Boo
Boy, you know I’m crazy over you


何をしていようが
私が考えているのはあなたの事
彼といるときでさえ
分かるでしょ　あなたに夢中なの



※　whatever = no matter what

     何が～しようとも

No matter what happens , I will always be with you.
