Ana-
After meeting Arjun in the cafe Ana's mind was in a mess. she did not know what to do. She never imagined this will happen. She always wanted to kepp her children away from Arjun. She never wanted to diturb his life. Whatever that happened for years ago was a beautuful mistake.
She coudn't deny the fact that she somewhat got attarcted to Arjun all those years. But she never acted upon it. His friendship more than enough for her and she never wanted to destroy that. And after getting to know that he had a girlfrind she never thought about the attraction she had for him again.
Ana knew that Arjun loved his girlfriend more than anyhting. he had said so. That is the reson she disappeared after that night and never informend Arjun about his children.
