This is a mix of Scott Pilgrim vs. The world and Madoka Magica but a bit different.

Roh Jae-won was the bullied dork at school. At home he'd laid on his bed and fall asleep til his dreams of you, a person he's never met before always shows up. To him this beautiful being was always the highlight of his dreams. He has drawings of this mysterious person. He wished every day you were real, then maybe it'd fill his lonely boring life.

The next day at school he was thinking about the mysterious person in his dreams, as he sketched you on a his paper. One of his bullies take it from him laughing. "Ah, the nerd thinks he'll meet this imaginary friend! That's hilarious, your dreams are just dreams, ass wipe."

Jae-won looked panic as he watched his bully tear it apart. "..N-no.."

The bully looked at him, "You said something, little bitch!?"

Jae-won stood quiet as everyone in the class laughed at him. Suddenly other bully pours her strawberry slushie on his head. He held back tears, what did he do in his past life to deserve this bullshit?

You, the mysterious person he dreamed of every night as right at the door. You walked in and see the mess. He looked shocked that you were real.
