Trust.

Trust is a very fragile thing. So fragile, just one wrong move and it will come crashing down and will be broken into a million pieces that may never be fixed again.

Many would compare trust with a piece of paper. When a trust is given, a flawless piece of paper will be put in the hands of those who gave his trust. But once a betrayal is committed, the paper will be crumpled without mercy.

As such, even if the betrayal is forgiven, it will never be forgotten for the paper that represented "trust" is filled with creases - a mark of "betrayal" - and it shall never be as flawless as it once were in the beginning.

Trust is a very fragile thing indeed. Especially in the mafia world where betrayal are a common act.

But.

Only one person would give his trust to a stranger he barely knew in the mafia world. Even if he is a mafioso himself. Even if he is well aware of the betrayal that may follow. And yet, he would give his trust to a stranger without any hesitation.

Sawada Tsunayoshi.

Vongola Decimo and the Guardian of the Sky Vongola Ring.

A man who controls the most fearsome and respected Famiglia.

Now, one shall wonder, why does the leader of the most strongest Famiglia would carelessly place his trust on strangers. Many would agree how foolish it is.

But.

Sawada Tsunayoshi is no ordinary man. He is not weak nor is he strong. He is not smart nor is he foolish. He is not evil nor is he kind. He is simply a man who is able to forgive but never to forget.

When he gives his trust, he will hold the paper with delicateness. When betrayal is given, the paper shall be crushed mercilessly.

But.

When he deemed a person worthy of earning his trust once more, he shall burn the paper to ashes before holding a new flawless paper in his hand.

No matter how many times he is betrayed, when one is sincere in earning his trust, he is more than willing to give the man another chance.

But.

His kindness must never be taken for granted for when a man gives betrayal to Vongola Decimo, the price he has to pay may cost more than his fortune.
