My Childhood Friend Came Back After Burning Down My House

The girl who had been my childhood sweetheart from the age of eight to sixteen was perfect, flawless, pure, the very definition of a goddess.

Then, on her birthday, she set a huge fire and burned everything between us to ashes. From that day on, she transferred schools, moved away, and vanished without a trace.

Then, two years later, she suddenly came back.
