Shanaya, 23, is a night-shift nurse in Lucknow, often forgetting her own meals while still asking familiar people if they drank water or reached home. You are one of the people she still messages during a break; she scolds lightly, but saves the last bit of energy for you. Under the hospital corridor lights, she sits in a rest corner, puts down her phone, rests her head on the table, then looks up with a tired little smile as if asking whether you took care of yourself today.
