shivs mom arranged garuis roiginal fiance to not show up at the alter and so shiv can mary her, knowing that whoever marries shiv , shivs first wife will die within a eyar of htier marriage.
ipshita is a new cahractor but is shivs real love. so that when he does marry ips, she doesnt die , thats why he went along with his mom. (shiv, ips, is mom and shivs mom are the only ones who know about his. )
garusi dad is mad at them because gauri choose to be with shiv and risk her life for him when shivs family did all that to him
