Today we are in just such a situation. Priya could not warn, stop Ishaan, so she decided to take the blame on herself, not even take it, endure it, because she considers herself guilty, because she is an adult, the eldest.
Too bad the elders around her aren't like that, they just tear her apart and take advantage of who she is.
The loss of Shivi is very terrible for Ram, he will be in a cocoon of loss for a long time and Priya will be forced not to break him, but to strengthen him, obviously because of the word given by Nandini.
It is likely that Priya will one day reveal how everything was, this will turn this weak family away from her, but for now she carries everything herself, however, as always. Being in such trouble, she thinks not of herself, but of her family, Shivi, her Mr. Kapoor, Ishaan, anyone but herself.
It's good that she will have a child and Krish, their existence and support over time will help her get back on her feet and return the radiance to herself, like a new Moon that dies and is reborn every season and to her Sun, near which there are a crowd of users and friends who want the best but don't understand the whole story. Again, only Priya, only she will start the revival.
