Trust is a very big word...
Once broken, it takes time to build along with fear... But who breaks it matters a lot...
I agree with parboni .. it's not love that makes us strong... It's our trust.. Reyansh realized now that he broke pranati's trust on him into millions of pieces already...
That's the reason, he was thanking her for allowing to put ointment on her back and also for promising him.
Both the things are for her benefit only but still he was moving very carefully knowing that he already broke her trust.. he had a misconception that he didn't deserve her... Real thing is he broke her trust many times not once but many times that it's difficult to expect anything from her...
We have seen a warning note by Rey to Archit for bangle's dangling.. Rey indirectly reminded him that pranati trusts him a lot... This is the truth... pranati really trust Archit as a friend...it doesn't matter who breaks our trust.. we will endure that pain for sure. Reyansh doesn't want anyone breaking her trust again like he did...
Rey has always warned Archit about his behaviour and you are perfectly right Pranati has a lot of confidence in Archit about their friendship.
Pranati puts its soul into everything it does, that's why it breaks so easily.
