They never showed shaurya and shagun’s journey but I think from recent episodes it seems like shagun was a student and later started working at SIAC. At some point they started dating cause they probably liked each other and since saberwal family needed bahu, shagun fit that criteria so he was like why not let’s get married.
And when they broke up, he didn’t even care or shed a single tear. Shagun and shaurya were together for two years and now in less than 6 months he is in love with someone else. So I’m not sure it was love.
But at this point before Anokhi expresses her feelings, I want her to think that does her PS have something for his students (because she is a second student lol) and how easy it was for him to move on from shagun. If shagun was just ex it didn’t matter but since they were almost engaged, anokhi needs to find out the reason for their broken engagement.
