Just what is a "true partner?"

This is a love story that depicts a whole new way of being a married couple.

Hiro Kamon is 45 years old. Her charm and serenely beautiful smile endears many, who fondly refer to her as a "beauty that stands above the rest" and "the ideal woman." But the truth is... she despises people

Her toxic heart is overflowing with hatred for others. Whenever she has shown her true colors, someone has always ended up being hurt. The only time she truly fell in love was in college, and even he ran away.

As a result of her past, she has shut down her feelings and closed her heart. She had made up her mind. "I will live alone forever." As fate would have it, a chance encounter with the man she used to love suddenly leads to marriage. Yet it turns out to be... a fake marriage!
