[The daughter of a wealthy daughter who can't endure any hardships x the super-controlling father who has known how to dote on his wife since childhood]
Key point: no blood relationship! ! ! The heroine was adopted when she was two years old. Because she was too young, she had no memory of her biological parents. Her adoptive parents did not tell her her life experience out of protection! But the brother knows his sister's life experience! His eldest sister is five years old! Because before the heroine's parents had an accident, when they were joking among themselves, they said that they would promise his sister to be his wife! So he kept remembering it!
Intention: pure love
