Spoiled By the Young Master After Reborn In the 80s

In her past life, she was his personal physician, his junior,
Due to the age difference, she could only bury her love for him deep in her heart.
An explosion awakened her, and she found herself back in his era.
When they met again, he was the noble and aloof scion of his family,
She was a village girl with a tragic background.
But this time, she would not shrink back,
She would bravely pursue her love, making this second chance at life devoid of regrets.
In public, he was cold and ruthless,
In private, he was a devoted lapdog to his wife,
His maxim was, “What the wife says is always the truth.”
This story is a one-to-one relationship, with both parties being virtuous and strong.
