Between I think Anu understand pre well...he knows pre wants social wedding and he himself proposed that... It really makes her forget everything that happened in her life.... Actually she is very happy and excited now...
Why don't we take pre's talk as cute banter... Because Anu said the same in komo track to make her move on... So maybe she's using the same now... But still she is his wife and both consider this marriage as marriage...
I think it was meant to be cute banter but so much foreshadowing has spoiled it for us
