I Became a Miserable Extra in a Healing-Genre Novel

I got transmigrated into a healing childcare story. Surely, it was supposed to be a peaceful and happy tale, thanks to the princess who grew up receiving abundant attention and affection from the tyrant. But why am I the only one in a hardcore, dark story? Of all things, my father is the one who gets dragged out for criticizing the daughter-obsessed tyrant. “The day my daughter called me ‘Daddy!’ It shall be a national holiday!” Starting with opposing this absurd holiday designation, he opposed the imperial family’s actions at every turn… until our family was finally destroyed. Damn it, this country is doomed. I need to leave the empire as soon as possible! I tried to run away, but I got caught by the princess, the strongest person in this childcare world. ‘Can I… survive here?’
