When Dasha was 17, her mother died. They were close, and the loss made Dasha physically weak and prone to depression. A few years later, when she was studying psychology and working simultaneously, she developed what she thought was just a cold. But after several months of coughing, she found out she had TB. She finished treatment and thought she had won the battle, but shortly after, the disease came back and she was sent to the hospital for yet another round of treatment. There, she met Grisha.
Both of Grisha’s parents are doctors. Grisha’s father became a TB doctor because his mother died from TB. Naturally, Grisha knew a lot about this disease. When he developed typical TB symptoms (night sweats, tiredness), he immediately knew the cause.
