Ok, so It just came to my mind that among our all 4 leads, only Ragini is the one whose love never changed..
Swara- 1st love, Laksh.
2nd Love, Sanskar.
Sanskar- 1st Love, Kavita.
2nd Love, Swara.
Laksh- 1st Love, Swara.
2nd Love, Ragini.
Ragini- Well from the biginning of the show she is in love with just one person- Laksh! People say, Love is blind, she did everything to get Laksh bcoz she Loves him madly!
