I was thinking what connects people?
Moments of happiness and grief have the power to draw people towards one another .Suffering is tough. Tougher environments creates strong bonds
Even with strangers during a journey together , train, flight or bus, common interests like weather , sports , music creates that link where you find yourself sharing convo for hrs together without even knowing the name of the person.
Here they hv quite a few interests/ pointers that makes them want to extend an ear to what the other is feeling/saying.
They have Aadhya and Nihar, strong interest ... Then they hv their office environment and the biggest pull, their own personal sorrows that makes them reach out to each other.
In a short time, how much these texts they hv come to exchange mean a lot to them is enough proof to that bond.
