The Prince and his wives

"What is love? I used to think that love was nothing more than a distraction but when I met her I knew love was more than that, I loved her but was forced to marry another."

Our main character, Li Tian You is the eldest legitimate son of the current Emperor's brother, Prince Zi. As you could tell Tian You grew up with both fame and power, but who would have known that under the mask of being the Emperor's nephew he was nothing but a puppet controlled by his father and bullied by his stepmother...

On the other side, there was the spoiled, stubborn but beautiful third Princess of Dong Yue, Li Chiu Yeung, Tian You's cousin. Because of her personality, nobody wanted to marry her. But fate had different plans, out of irresistible circumstances, Tian You ended up betraying his lover and married Princess Chiu Yeung.
How would these two lovers cross paths as they set aside their differences? Especially since Li Tian You blames Chiu Yeung for the death of her father.

What would happen when Tian You's sweetheart, Lin Xin Er comes and finds him? Will Tian You and Chiu Yueng finally set aside their difference and find love or would Xin Er's appearance ruin everything? Or would both girls become part of Tian You's harem? And what secret does Xin Er herself hold?
============================================
Let me make myself clear this is not incest as the main characters aren't related. You will see why during the story. The plot and all the characters are original. It isn't translated. There might be some grammatical mistakes as English is not my first language. The book cover isn't mine, I found it on Pinterest so credits go to the artist.
The timeliness is based in ancient China.
It's for both genders to read, but maybe a bit more for females cause it's mostly a historical romance.
