Instead of hiding the fake pregnancy belly from Doggy-FJin -Goo, Dumbo Ha-Na could have let him see it and got Eun-Choing to repeat what he had told her. All three of them could have gone to search Mama Biatch's closet together and found the rest of the fake pregnancy bellies, for various stages of pregnancy. This would be a better option than waiting to expose the scam on the wedding day; the sooner that she put a stop to the adoption by the bitches the better.
