The Chinese lyrics of Destiny include the following: I don't know much about love. I never thought that love would come like this. In front of love, my heart is still not so stable. If I knew this, I wouldn't have started. I'm like a fool. I regret it now. I'm praying that you don't love me. I'm praying that the person who loves me shouldn't be you. You've been lying to me. There can be no love between you and me.
I don't think so. There haven't been any official announcements or indications that the HxH manga will continue. But you never know, maybe there'll be a surprise in the future.
