Tsuna learned young that he was not his parents priority. So he never said anything about the itch under his skin, about the way he sometimes felt his body burn from the inside or how the only time he felt calm was when blood ran like rivulets down his skin. [Or the one where Tsuna finds a family for himself and subsequently starts taking over the world (by accident)]
