Hero-ui Namchinindeyo?

The most famous hero x ordinary person couple at the moment, Devil M and Jung Na-na, also enter a period of inevitably boredom after 10 years of dating. But one day, the love bead containing the will of the villain who has been tormenting Devil M bears fruit in Jung Na-na's body, and their boredom flows in a new direction.
