Tsunayoshi Sawada, right... that was his name.
Tsuna was abused, because he was useless.. he really was.
He knew he deserve this things he got. He hated everything, including the world.
Even his smart, perfect, brother hated him.
He was content with it.
Not really serving a thing.
Except, as a sacrifice.
Yes, he was a waste. A waste that serves as a sacrifice to the world.
He really was content.
So, he will smile, the only thing he can do right.
Even in hardest times, even if he can't anymore.
After all, even though not necessarily, he is a sky.
And, even if he was really useless at being one, he will smile.
Even if, he was broken beyond repair.
