One day, after collapsing, Fiona remembered her past life memories and realized she had been reincarnated as the villainess.

"Yay!"

Even though she's the villainess, her family is a wealthy Marquis house, her parents dote on her, and since she hasn't bullied the heroine yet, she might be able to avoid condemnation.

Having been a corporate drone in her previous life, the premonition that she could finally take it easy, unlike her past life, made her feel elated, thinking, "Isn't this lucky!?", but she quickly changed her mind.

This body is too sickly!

She gets dizzy and collapses under strong sunlight, collapses with heart palpitations and shortness of breath if she runs, and eventually, collapses even when doing nothing.

This wasn't in the official settings, was it!?

Now she understands. Why the game's Fiona was the villainess.

She must have had no choice but to lash out because she felt so unwell.

However, she can't live a carefree slow life like this!

More accurately, she can't endure feeling so unwell!

Fiona tries to make an effort to improve her health, but... to begin with, this world's understanding of sick people is poor.

Why do they serve steak when she says she's feeling unwell!? To build stamina? She can't even eat it in the first place!

That's enough! I'll manage it myself!

For a comfortable life, Fiona resolves to get healthy using her modern knowledge.

Then, Louis, a capture target from the game, her fiancé, who used to have a strained relationship with Fiona, and the Duke's heir, undergoes a change...?

"I won't let you get away."

"From now on, you can tell me anything. I'll grant your every wish."

Th-that's strange! He's too sweet, unlike in the original story...!

Unaware of what her efforts for her own health would bring about, Fiona collapsed again today.

A romantic comedy about a sickly villainess whose efforts to get healthy unexpectedly impact those around her, and her fiancé, who becomes obsessed with her and turns dotingly overprotective!
