I have dual mind about letter
One malhar wont read it and kallu Jo himmath jutake malhar ke paas aayi he will go back
Beacsue rachit ka end nahi huva na as of bts. So even if samhar needs marriage I mean even if malhar agrees for that he won't let rachit stay with kallu as he knows it is dangerous and once kallu admits marraige was fake there won't be any way that rachit can stay as malhar is back as ACp so they will have to end rachit once malhar knows the truth
Other yes malhar will read that letter and let us see what is in store.
