Reina grew up feeling unwelcome in the Faluane Viscount household.

She was even told not to practice magic, as it was deemed too dangerous. Her younger sister, Almia, on the other hand, was doted on by their parents and raised in an overly pampered manner.

Reina had endured her sister's selfishness and her parents' almost abusive treatment, but then a marriage proposal arrived from a Duke's son. Just when Reina thought she could finally leave the house, Almia took a liking to him, and her fiancé was snatched away.

However, Almia returned him again, complaining that the Duke's family was quick to scold and too overbearing.

Reina wondered why the gentle and humble Duke's son kept changing fiancées so frequently.

It was Viscount Faluane's clever trap.

Reina came to live at the Duke's mansion as a temporary fiancée, and there, she was finally able to activate the magic she had long desired.

Reina was excited, wondering what kind of magical attribute she could manifest.

The magic Reina activated was legendary healing magic.

Reina found the very act of activating healing magic enjoyable and delightful. Driven by her desire to use magic, she began saving various people with her healing abilities.

Furthermore, at the Duke's mansion, she spent her days being pampered, and her life became a truly happy one.

As she spent time at the Duke's mansion, it was revealed that Viscount Faluane was the reason behind the repeated changes in fiancées. After their mutual misunderstandings were resolved, she began to be doted on by the Duke of Julight's son.

Reina's life becomes happy with her leisurely days at the Duke's mansion, the doting affection from the Duke of Julight's son, and being cherished and loved by various people through her healing magic.

Meanwhile, at the Faluane Viscountcy, with Reina—who had been responsible for curbing Almia's selfishness—gone, Almia's self-indulgent rampage began.

She ruined valuable marriage proposals, spent money recklessly, and did whatever she pleased.

Furthermore, Viscount Faluane's misdeeds gradually began to come to light...?
