Ye log ne full YHM chhapa hai Matlab. So they eventually what happened? When the FL came back, how did the plot progress?
Not only Ghum, but even other shows have made a joke of surrogacy. First YHM, then in YRHPK, the antagonist (Kuhu) becomes the surrogate for lead couple and creates so much drama and tension for the FL who is baby's bio mom. It's ridiculous.
@Shree15 explained thoroughly what happened afterward. The plot is basically surrounding the other kid who they had presumed dead. It was too painful for ML and in-laws to talk about FL and their kid, so they removed all memories of both of them. Even though ML faked marriage with vamp, audience could tell it was empty. They didn't live in same room, they never really interacted together in any real sense. ML was always in memories of FL, angry at life and fate for taking away his wife and daughter seven years ago. We hated the writers for the storyline, but we could always tell the ML's one true love was FL, not the vamp. But they never show that intensity for Virat and Sai.
