Looking bat how carried away Bon is, I don't think Ani's soft convincing or unreasonable harsh outburst will push her to give up. It must be the truth that he loves manorama.
When she hears him confessing it, it will definitely break her heart. Despite her being with him for an year, through thick and thin, caring for him, not giving up on them in spite of multiple rejections, if he chose to love another woman, who he met few days ago, just because she is grown up, then it will make Bon realize there is no point in trying for a non existent relationship. She will not pay heed to KSJ or society as well.
I think that will be enough, no need for second marriage. Marriage is not a child's play. Second marriage of Ani should happen when Bon is grown up and they both decided to keep it as mentor-mentee, friends. Bon can find a guy for herself and Ani, a woman suitable for him.
Even though, Ani-Bon don't share the conventional marriage, it will be very regressive to show two wives for a man. It is disrespectful for both the characters. The imagination itself makes me cringe.
Anyone can gimme hope that it will not happen. They can't destroy Ani, they should not completely for drama😭
