The continent’s guardian who led the war against the demon realm to victory and a ruthless businessman.

A man who never misses an opportunity that comes his way.

Caius von Elbartan.

The salvation that appeared to him, who had been under attack by mysterious demon beasts for a year.

The princess of a crumbling kingdom and possessor of a special ability.

Ariel von Retiana − The princess who proposed a one-year contract marriage possessed the healing ability he desperately needed.

Caius gladly accepted her proposal.

In return, he planned to bestow many things upon her.

It was clearly a marriage advantageous only to him.

Until he learned the truth.

The demon realm flower growing with her plant growth ability in the greenhouse was a plant that would kill him.

“Did you enjoy it? Did you feel ecstasy watching a man suffer because of you? I never thought. That you, so noble, would have such a sadistic hobby.”

Caius decided to keep her by his side and torment her.

Until he got what he wanted.
