Ek aur baath he
Pillu ke ane ke baad hi ab aaye he
Ab tak kalma was adhoora ( not sr thing I mean ) without pillu and other issue now they are a complete family
And athu and sampu if she is also there can't bear kalma being happy
So ek aur possibility he to disturb their life
Moksh was brought up by aparana he has never know her parents
Ahir , kalyani and Malhar told him they are his parents he believed that probably as he liked kalma
The kids mind is pure
Even if he is malhars son athu can shower love on him
And tell him that he is samtharava ka son
And not kalmas
Kids can be made to believe such bakwaas na
Especially a kid who has never seems it's parents before
Whose relationship with kalma ( when he has memmory) is of less than six months can be easily misguided or seeds of doubt can be sown in his mind
