Princess, Who Changes Bodies and Then Gets Developed?

After transmigrating into a book as a minor nobody, Noli knows all too well that if she wants to survive, she has to find the heroine and get on her good side.

But before she can do that, she somehow swaps bodies with a silver-haired girl named Miya.

No way! If things keep going like this, no matter how hard I work, someone else will reap the rewards. Give me back my body!

Before she can put her plan into action, Noli unexpectedly discovers that Miya seems to have some connection to the heroine.

Whoa, you're more than meets the eye~

Hehe, I'll use you to find the heroine.

Once I find her, I'll dump you.

Some time later...

After going around in circles, how did it turn out to be you?

Phew... Good thing I didn't dump you.

I almost went through all that trouble for nothing.

But why has Miya started looking at her so strangely?

"Um, it's a misunderstanding. If I had recognized you, I wouldn't have..."

Let's talk this out. Don't hit me, and don't actually use your mouth either!

"Hey! That's your own body!"

"Enough talk. This is your punishment."

Huh?

Since when is making use of someone's body a punishment after swapping bodies?

"Stop... Stop it... Don't use your hands..."

"If you don't want me to use my hands, does that mean you want me to use my mouth?"

Eek!

She did manage to get on the heroine's good side in the end, but why did things turn out like this?
