crossing to become the follower of the vicious female partner EP21

⁣⁣⁣⁣⁣⁣⁣⁣[S⁣ynopsis] I crossed over into the novel and became a very unimportant character: the henchman of the vicious female partner.
The protagonist was originally a poor migrant worker, who crossed into a brain-dead novel after working overtime and became the follower of a vicious female partner. I didn't expect the vicious female pair to be very generous, and she gave luxury goods and money.
The protagonist began to use his foreknowledge of the plot to help the female supporting actress escape from the original story ending, and in the process, he fell in love with the seemingly pampered and domineering, but actually simple and kind 'vicious female supporting role'.
