They just don't suit each other and in my opinion they are not gna get together as it would be too simple and straight forward if that happened. Rukmini would want a daughter in law who is simple and sweet who won't question her authority. Sanju is opposite that so don't see this Jodi being successful.
When CVs try to impose a couple on the audience that don't suit they give them way too much screen space which is what is happening.
Bottom line for me is Yash and Sanju don't match up well according to me.
