1.Ashu tried to tell Nidhi that Amar is in love with you. Nidhi told that he said we (Ashni) are perfect couple.
Nidhi tried to tell Ashu that Mallu is in love with him so she tried to separate them. Ashu told no its your idea coming from immaturity.
Mallu had a track record where she tried to separating them but Amar has not.
2. Ashu told Nidhi Amar's background is not clean as his bhai is gunda, Nidhi didn't trust him.
Nidhi told Ashu thah Mallu is faking her illness and lying about Nidhi. Ashu did not believe her and accused her for attempt to murder.
Mallu had track record of foul play and telling lie but till now Amar is a sarif beta of gunda family.
Then Ashu believes Mallu over Nidhi and now Nidhi believes Amar over Ashu.
Bottom line Ashni love each other very much. Trust for each other is there but they don't trust each others views towards others.
Mallu had always try to harm Ashni's relationship lets see what Amar is upto.❓ Hope Amar's presence will help them to come closer.
Oh God! Please re-unite Ashni Asap. Amen.
