Ki the show is stepping towards its end
Reason for my thinking
As you have seen kukkuji's reaction on r.k.'s condition
May be they are planning to correct all negative character
As madhu might saves r.k.
Or if she left r.k.
Then when r.k. come in sane
He might ask abt her
Which will result in his anger
May be and result in happy ending
I know I m reacting very short tempered
But still
