Princess, Your Secret Identity Is Showing

Because of a “binding error,” a princess who transmigrates into a book and becomes a cannon-fodder supporting character gains a “shared-sensations” buff. With a soul from another world, she and the characters from the book retrace the original plot...

The princess is about to poison someone? No way! She knocks over the poisoned wine and rubs the male lead's stomach. The villain is going to assassinate someone? No way! She gears up from head to toe and acts as his meat shield. The princess is going to have the male lead's baby? No way! Sob, I can't have a baby...

She fusses over him like a mother hen, while staying as cold and distant as a flower on a mountaintop. The male lead is exhausted: “Princess, you really make it impossible for me to let go!”

Then one day, the “shared-sensations” buff upgrades. Now it lets her share not only the male lead's physical sensations, but also resonate with his emotions... So, can you feel my surging feelings for you?
