Reborn, Reincarnate, Recreate

The story of a young boy learning to love himself. "I lived a content life, and then I died. But that's not the end. Apparently, I was reincarnated into one Sawada Tsunayoshi. Whom I don't know anything about, since I don't watch anime. Hahaha... help me." Not a self-insert but you can take it as such. Tsuna's still going to be Tsuna, after all. Just with different motivations.
