That was a vey cute scene. It did show that Bani still loves Jai. There was longing in her eyes & not hatred which we saw till now.
Also I noticed Bani was watching Jai & Jai even thouh looking at her windi=ow didn't see her at first. HE was about to leave when he noticed that Bani was there. When Bani realised that he is string at her then only she closed the curtain . So if he didn't know she was there she would have kept staring at him😳😳
