Icha knows Tappu very well....infact even when Icha was small, she analysed Tappu's behavior accurately....be it when first Tappu hid Ichki's homework book or be it , Tappu leaving Icha at the zoo purposefully or Tappu being happy that Ichki was not the lead in the dance show, Ichki knows it all, no one else knows but Ichki knows .........and even now , Tappu hasnt changed , she still gives torn dresses in the name of "affection" , and Icki knows all this and still manages to genuinely like Tappu ...I mean its not just like, its real concern and affection....Ichki is too large-hearted, I could see and hear the gratitude she felt for Tappu while she was discussing about Tappu to Veer....
