It was always about Abhigya&their connection. For some reason they married quick&definitive,without hiding and after a lot of signs that they're meant to be despite being so different. All was there:
-her failed attempts to marry/get engaged to anyone else
-him having gf-bf hidden relation with T and being rejected when he wanted to take the next step
-mangalsutra lifted by both
-sindoor covering them
-the darkness turned into light at their wedding-the kind of life they will have together or not,with ups&downs
All signs that they will eat each other's days forever,wanting or not,can hide but can't escape their fate.
