It all stems from an inconspicuous but dark little secret.
Everything should have kicked off three years ago.
But I couldn't help myself, until three years later everything changed and I came back to "revenge".

Can I really let go when I ruin everyone's lives?
This is a darker story. But after reading it carefully, what I want to express is actually not hatred.
It turns out that everything is based on obsession.
