I never thought I would say this first but here goes: I liked Dipali! And Thank you Dips!
I will start with your comment about how you had planned on ending the story and then followed your instincts. Please. Always. Follow. Your. Instincts!
I truly loved this ending better. This version was unexpected but it made complete sense!
Of course RK would be questioning why Madhu agreed and he would be questioning why does he care that she changed her mind. This RK is not shallow that all he wants is a ahem ahem but he truly cares for her. So it made complete sense and I loved it!
RK stopped and thought about the situation and his feelings and then with Dips' help he confronted Madhu.
I honestly never want your stories to end! I started the story and then I had to leave it half way. When I came back, instead of picking up from where I left off, I went back to the start just because I wanted the pleasure, the enjoyment, to last longer!
