There is a twist before marriage. Harman asks Surbhi to come and meet her. They meet and have a talk. Harman tells Surbhi that he is helpless and can’t marry her, as he loves Soumya. He says I love just Soumya and can’t think of marrying anyone. He asks Surbhi to refuse for marriage.
Harman can’t have anyone in his life except Soumya. Surbhi is also helpless and can’t refuse for marriage, as she knows about Preeto’s condition. She can’t tell Harman about Preeto’s condition as Soumya made her swear not to tell this truth to anyone. Surbhi knows Soumya has no option, Soumya has no roof to stay. There is no way or helping factor for Soumya. Surbhi is giving a big sacrifice for Soumya.
