When I was fifteen years old, my master told me before he died that I was the child he picked up from the snow.
"The knife beside you is called 'Buyu'. When the knife is taken out of its sheath, it will drink blood."
Ten years later, I became the number one killer in the world by virtue of "Buyu", killing countless dead souls.
Until I met a woman whose birthmark on the back of her neck was exactly the same as the one in my dream.
The moment I put the knife away, I saw clearly for the first time the small words on the knife: "The one who holds the knife will never lose his love."
And she smiled and said to me: "This knife was originally mine."
