Saras, is better off without the two "mindless" and "fake" sisters. Kusum is shameless, thankless, selfish, and has no concern about anyone except herself. Kumud is impulsive, feels that she is always right, and has Saras dancing to her tunes.
Kusum says, "Mein Saras se pyaar karti hoon. Muje woh chhiye."
Kumud says, "Saras mera hai. Lekin tuje chahiye to tu le le. Mere pass stand by Pramad hai" This means that she thinks of Saras as an object that she can gift her sister to keep her happy. Will the sister be happy ever after? If Kumud actually loves Kusum, she should teach her what love is... so that she can lead a hppy life, not give her everything she asks for.
If Saras stays back "for his love" he will NOT get it, but end being a ping-pong ball between the two sisters.
