i am with both ...but 70% with arti n rest with yash
lets hav a look
yash remembered everything of that night but arti doesnt ...
arti made a promise to yash that she will never take arpita's place...
yash dont want to go to mumbai but arti made him agree just for arpita...
yash said to himself that he will never giv arpita's place to anyone...
arti n yash married for their kids n they said to each other that they will stay as mom n dad of kids n not as hubby n wife...
coz of arti all arpitas memories burned ...thought arti did not did it wantedly...
yash accepted it ...
yash n arti both got drunk ...
yash remembered everything...n he thinks arti betrayted him...
yash feelings
he had broke his promise to arpita...arti broke his promise n trust...he trusted her ...its thing that cant be shared...n yash is in sudden shock ...n he got more angry to see arti behaving normal as if nothing happen...
in that sudden shock...i think he did not saw ans machine also...n its not about prashant truth...
reasons
yash never asked arti about her past...
arti bechari...we all know
