1. RK prove to Madhu he loves her n will never break her and try hardest to do this
2. Madhu sees RK's efforts and realises she is not RK and he has made amends and she doesn't want to break RK or his mums heart as she doesn't want them to through pain she did but wants RK to understand what he did and wants him to apologise
3. sultan to become negative ..for this to happen madhu needs to insult sultan or sultan wants to bring madhu aganist her will and she finds out his feelings for her and rejects him and he becomes negative
Or 4. Aryan gets killed or critically injured by Bujang but its shown in Sultans view that RK did it and Madhu stays on RKs side because she saw it and sultan kidnaps madhu to hurt rk and hurts her physically and his heart has gone and he has changed like become like bujang
5. Rk knows madhu is playing a game with him and all these times we haven't seen him onscreen is because he is spying on her wanting to know Hw far can she go n organising her to be in a movie also rk noticed madhu n sultan talking at the gate and then she walked off.; cvs can show that rk followed her to her mums house and showed her talking to her mum and her plan of teaching rk a lesson
So basically both are playing games
I believe any of the above will make show more interesting
But making sully negative will be the best
