Sometimes, as we go about with our lives, we all happen to think of one specific thought at least once.

“Rishe Ilmgard Wertsner! I’m breaking off my engagement with you!”
“Okay, I understand”
“Huh.”

The Duke’s daughter, Rishe left the evening party without delay.

In fact, for Rishe, this engagement has been terminated for the seventh time. And that’s where her new life starts, having enjoyed the way of life of a pharmacist and a dressed up knight, she lost her life at the age of 20 and now has gone back to the scene where her engagement was broken off.

Normally, this could have broken Rishe’s heart, but her mentality now is strong.
Her past six lives have been busy and fulfilling, she wants to live longer this time around.
If possible, she wants to live a life of leisure and squander money….

To commence her 7th life, Rishe has set up such a diagonal goal.
However, in this life, she will be married to the Crown Prince of a militant nation, who killed her in her past life.

…….. It’s probably better. It doesn’t matter if it’s a former rival country. In her seventh lifetime, she’ll enjoy loafing off at a castle!!

Against all her determination, she inadvertently demonstrated the skills she had cultivated in her past lives and garnered attention as a brilliant Crown Princess.
