I knw ur worries !!
About Sadhna and Ranvir, yes we werent sure whether Sadhna gets married to Ranvir or Aalekh, but both had 50 50 chance actually 60-40 Aalekh has 60% chance so that was good, as Sadhna and Alekh make a very cute couple, and the beauty was if Ragini wud have married Aalkeh which also was thought then after being cured she wud have a struggle, but i find Saalekh presence more beautiful onscreen seriously... coming back to Ranvir Ragini, I love the track before go, there were also thoughts about RagVir being a couple the day Ranvir first met Ragini,atleast i wanted to and makers did full justice to the track, about Shushir, few say he play cupid/mediator and help Ragini Ranvir to get back, i want to believe that as he was a cameo but i dont want his heart to break either.... Out of many reasons i think RagVir wud be together as The color issue wud be up in her sasural if she is wid Sadhna as her mother thought, VAsu and Avni wud defo try making things not easy for Ragini and how she overcomes that struggle wud be a must watch!! Secondly RagVir love each other and they deserve happiness, though Ranvir needs and deserves repence and struggle before he gets Ragini, roads wudnt be easy for her!!
Luv,
