I'm very sorry! I didn't mean to do that!

Oh, nothing to worry about. I'm not hurt in the least!

I'm still rockin'! Explanation: Even though it's an arrow pointing to Kaito, the phrase "Gu Rock" is something a person says, and it usually means "I rock." However, if I had kept the translation simply as "I rock," its being a pun/joke might not have been as obvious.
