Obsessive, possessive war-god prince top x sickly former general bottom
The young general Xie Zhao suffers a crushing defeat, and his marriage contract is returned to him.
But Xie Zhao won't back down. He sends back a divorce agreement of his own.
Wrongfully imprisoned, he is forced to drink poison.
Unexpectedly, he survives.
Half a year later, Xie Zhao is living under an assumed name when he runs into his former lover.
He thinks it's an unavoidable clash.
Instead, his former lover, riding high on success, knocks him unconscious and takes him back to his residence.
Xie Zhao: Your Highness, Prince Qin, we're divorced. What more do you want?
Xiao Pang: Xie Zhao, won't you stay?
[Bonus scene]
Xie Zhao used to think Xiao Pang was the most coolheaded and self-controlled person around.
Until one day,
he found a book by Xiao Pang's bedside. It was titled The War God's Princess and Her Discarded Husband, and had a military strategy book's cover slipped over it.
Xiao Pang read it every night, calling it study material.
Xie Zhao picked up the book, ready to tease him.
But Xiao Pang caught him, cornered him by the bed, and made sure they studied it together.
Notes:
1. The bottom injures his leg at the beginning, but it gets better later.
2. Both are sexually inexperienced, happy ending, one-on-one.
3. Mild coercion.
Theme: Safeguard unity.
