Sahir is one hell of a complexed character I have seen on t.v.
He hut himself for hurting her yet stand still to let it go in front of her.
He pleads his mom to stop her and taunts himself to let her go of what ever they had .
All I see is love is sacrifice from sahir's side right now he knows very well he cannot stand by Arzoo with his martial status and he doesn't want to hide the truth any more to the innocent Arzoo.
Zaki is not wrong here after all some one needs to give a reality check to sahir not that what ever he did is wrong but no one knows why he did that ?
Totally a heart touching episode from arzoo's pain to sahir pleading and hurting himself ...oh god this is one hell of a love story.
