There's no such thing as coincidence. There is only inevitability.

My kindness gave happiness to others and began something good. My sorrow is ending everything and I am left only with an empty shell.. お別れ ---

...you'll never have enough clues..

"There's something beating here inside my body
And it's called a heart
You know how easy it is to tear it apart
If I lend it to you, would you keep it safe for me
I'll lend it to you, will you treat it tenderly?"
