My best friend accidentally transmigrates into a book and, on the very same day, marries a pair of sworn enemies: the two cannon-fodder uncles and nephews from the story!
On their wedding night, her husband grabs her by the throat and curses her for drugging and scheming against him. She kicks back and threatens him with divorce.
My best friend goes even further, smashing her husband's head with an ashtray. The two of them break open the safe in the middle of the night and prepare to run, but just as they reach the airport, the System's icy prompt rings out: Mission incomplete.
You are not allowed to leave!
A few months later, everything takes a sudden turn...
