Transmigrating into My Fair Princess

This was an extraordinary adventure, and I was lucky enough to go through all the ups and downs with them.

As the lyrics say: Seize the vigor of youth and live it to the fullest.

This time, I'm the protagonist, but I want to change their fates and spare them some of the pain, because my feelings for them have grown deeper and deeper.

How it ends may be happy or sad, and the answer will be different for everyone.
