Jeonsaengui Wonsuga Apparagoyo?

I lived to the age of 19, only to be constantly taken advantage of by fake family members. With the vow to seek revenge still fresh in my mind, I made the choice to live my life again. Yet why have I returned to the night I was kidnapped from a burning castle?

"Hwelp me! Hwelp me! The willian ish twaking Maedie!"

My savior ended up being the enemy's son?! For days and nights I followed him to the enemy's castle, but upon arrival, a warm welcome...

"Ack! Father! Second Brother's picked up another living thing!"

...wasn't what awaited me.
