Baek Tae-se, a genius pianist known as the "Second Beethoven," seemed to know nothing of failure. However, his artistic world is shaken by a severe slump.

In front of Tae-se appears Kang Seol-ah, who breathes new inspiration and emotions into him. Tae-se offers to repay Seol-ah's debt of 215 million won, but in return, he demands her body...

"1 million won."
"I’ll reduce your debt by 1 million won each time we sleep together."

I don’t know what’s driving me crazy,
But you belong to me, Kang Seol-ah.
