The Wild Princess and the Foolish Prince
After a transmigration, she unexpectedly becomes the third young lady of the Prime Minister's mansion in the State of Chu. What? This third young lady was actually born to the Prime Minister and a maidservant after he got drunk? But she's still a young lady, with no worries about food or clothing. People in the mansion don't treat her kindly, but she endures.
What? The second young lady is betrothed to that foolish Prince Jin, but she refuses to marry and wants the third young lady to impersonate her? No matter what, she's still a princess, and it's none of her business if the prince is foolish, so she'll marry him. Once she's Princess Jin, she'll be arrogant and domineering forever.
What? Her own sister tries to force her way into the manor, and upon seeing the princess, doesn't kneel? Drag her out and beat her to death with clubs!
What? Someone dares to bully him, relying on the prince's foolishness? Don't they know this old lady is fiercely protective of her own? Drag them out and beat them to death with clubs!
But is this prince truly foolish or just pretending? How can he act so foolish and cute so perfectly?
