Mr. Contract Spirit's Development Plan

"Would you like to form a contract?"

At a turning point in her fate, a girl meets a contract spirit: elegant, mysterious, and powerful.

They form a contract, and the girl and the spirit open their hearts to each other.

Just when the girl thinks they can be together for all eternity, she discovers that something is not quite right.

"Su Xiao! Just how many people have you gotten involved with?!"

(This is a story about people who understand better than anyone how impossible it is to make sense of fate, yet still choose to fight against it.)
