It's just that your breasts are too flat! Can the ladies' clothing boss be more dedicated? Someone: Little girl, would you like to say it again? Let's see how the good-for-nothing eldest princess pretends to be a pig and eats the tiger, fighting monsters and upgrading her skills along the way to win a handsome man! The male and female protagonists join forces 1v1! That's it for the fun. In the early stage, it's a bit restrained to pretend to be a pig and eat the tiger, but in the later stage, it kills everyone!
