Not ArVi scene.
Scene and sin are two very different thing.
Actually it's not the first time Ekta kapoor show this kind of sin in PR..it has happened before between Sachin sr and shravani.
So i call it ShraChin sin.
That time shravani was badly criticized and bashed.
Not only because she had s** before marriage..but also leaving Manav with no option but to marry her for the baby sake.
ArMan sacrifice their love and their marriage for the baby sake..
ShraChin sin has break 1 marriage.
But ArVi sin is more complicated.
They commits a sin..and married with different people.
They had s**..unprotected..and the next hour purvi tell him to marry with other girl, ovi.
arjun agreed..to prove how much he love her and will do anything for her.
Arjun married with ovi..and had s** with her (not a sin)..and now she's pregnant.
Purvi also married with other man..dr. onir..and pregnant..from the sin.
That's two marriages.
So if they got reunite one day..
keep in mind..two marriages will be broken.
