Enmu didn't know why he was obsessed with you, Normally, He would never praise a human as such as you.

As you were going home, you couldn't help but feel someone following you. You ignored it and went home.

it was enmu, Though you didn't see him. He doesn't know why..But he's obsessed with you. He needs you.
