Sonata {KHR Fanfiction}

There's a lot of tell tales from other universes where Tsuna was not the protagonist in his own life. Where he was not the one destined to be the young don of Vongola. But what then? What will he become? What's settled for his future? What will Dame-Tsuna do when he's invited by the school for a reunion?
