With that song there are no past bits shown from.both sides. He simply laughed after crying because he knows she is with him so kept quiet. When Abhi came to meet Ak in music hall that time she told him to go away and he was angry on her going. Ak connected those bits where he is angry and hurt and had that song .she is reassuring him with her love that way. He already does much no need of him to say much. His only option is bhaag chale if none agrees. But he is bending for her wishes of families acceptance. So he is toned down lil bit.
Jo wada kiya is one of my all time fav.
We are seeing Akshara being traumatized at the thought of him leaving her. How come we don't see anything of that kind from his side? Not asking for a repeat of the heart-breaking / agonizing Abhimanyu but... Wouldn't he want some kind of reassurance or...something from her?
Is he being / forcing himself to be strong because that's what Akshara needs from him now?
