With the storyline going in parallel with Ekta's previous serial Koshish at the moment, Kkusum will teach Abhay A,B,C etc. Kkusum and Abhay will go to USA for Abhay's treatment.
In Koshish - Kajol and Neeraj went to USA. Neeraj's mentality was of an approx 8 yrs old - playing with toys etc. and Kajol teaching him how to read and write.
What do you think?
