My Princess Is Not Allowed to Run Away

[Sweet, gentle little princess who isn't weak x domineering, unhinged crown prince who later becomes king]

Elroy, crown prince of the Moonlit Star Empire, initially wanted to raise a sweet, obedient doll.

But the doll wouldn't behave. She had another man in her heart and kept trying to escape from him. How could he possibly tolerate that?

Elroy's doll would face his endless punishments.

Elroy's interference and cruel possession drove Sidilia completely over the edge. She would seduce him, win Elroy's heart, then cruelly abandon him.

In the end, his doll succeeded in stealing his heart, and even took his child.

But hadn't Elroy stolen Sidilia's heart too?
