Same I was like those two don't fit together. Unless he said it like a promise so it won't happen again?
I think it was supposed to be "te lo giuro", which means "I swear (to you) ", but when dealing with foreign languages, especially Italian, words are often put with the literal translation, without checking if it actually makes sense of if it is the correct word in that contest
he explains it in the next chapter.
@Newheart97 that would make sense!
@fujomom you made me curious xD
I know its meaning in Italian, but I can't understand why he says "I'm sorry giuramento".
