I think DM was right B'coz the persons whom he trusted more then his own self they cheated him for long time.
But SANTU is also correct B'coz what she done it's just for DM & TARU relationship. Not for her own purpose.
I don't think DM gives correct punishment to SANTU I know she made a big mistake but for this he can't cut all relationship with SANTU.
He should not forgive SANTU for this but he can't give this punishment SANTU at all.
I can't decide what would punishment he has to give SANTU.
She should say sorry to DM & she should try for winning DM's hart again.
