Fine Shlok was worried when he couldnt find Astha and he started to mix his past and present but NOTHING and I mean NOTHING justifies slapping Astha. If Astha just accepts this and wont say anything - I will be furious.
Even the preview Shlok proved to us he is planning something horrible against Astha. I dont care what he does to Astha for revenge as long as Astha doesnt fall in love with before that. I dont want Astha to fall in love and then Shlok taking revenge - that will be cliche.
