Tats how I see it
Gauri wud be planing to marry Shashank. Everything wud be going fine but ten some of Shiv's mean relatives wud create misunderstandings between Gauri and Shashank.. They will label Gauri as a fraud and a cheat.. Shashank wud refuse to marry Gauri on the wedding day.. Gauri's dad wud be heartbroken, he will beg Shashank to marry Gauri, but Shashank wont agree... Gauri's dad wud be like Who wud marry my daughter, and wud cry tat his family's rep has been ruined and stuff. Ten our Hero Shiv wud come from behind and SAY "I WUD MARRY GAURI" He wud marry her... Later he will tell Gauri tat he doesnt believe in love and all and just married her to save her family's rep.. And Gauri wud be all sad and stuff.. Ten later Shashank wud find out tat Gauri was innocent and tat she was framed.. He wud try to chase down Gauri, who wud say tat she is married, but Shashank wont give up.. Now the triangle wud start.. Shashank wud be after Gauri, Shiv wud start gettin jeleous and Gauri wud be confused between Shiv and Shashank...
