My selfish self says to hate you for deciding to leave Reborn - even though it may be for a short while. You were one of my closest friends in Reborn and having to say goodbye (albeit it temporarily) is very difficult. The humorous daily battles we had helped me take my mind off things and literally did make me laugh often, so its sad to realize those will not be happening anymore.
Nevertheless, if taking a break from Reborn means you, yourself will grow and mature, then I won't stop you (not that I have a choice xD). I hope to see you back someday though. Will miss ya pal. Best wishes for you.
