Where as Raju faking wont fit to the situation now... and the Bond they showed between him and Madhu will also look Fake.. and all those Kahna Connection too... there will be soo many unforgettable Bloopers ...
About Passionate Romance between RM2.. its quit Possible even now..
Now MAdhu likes and care for Raju.. but once he is normal and not remember her.. he may hate her for budding in between... and he can have MUs about her.. and can even say something bad to hurt her... making her hate him.. Later Destiny can bring them back together... then they will hate eachother but still have that unknown Pull for each other...
If AS and his Creative tean can pull the strings Perfectly.. then they can bring the Passion in Story for sure...
This is just my view...š
