One day Riju’s world was shattered when she introduced Riju to her fiancé, and calls him her brother. Riju got himself drunk, and all the friends left him alone outside the bar. While returning from the pub with Dola, Bapi realised that he must have got some feelings for Dola. One day, when Dola came to Bapi’s house, he asked Dola “who is Bishwayan da?”.
