What expression did Koly observe on the faces of the sick people by the river?

In the context of Koly's observations of the sick people by the river, the expression of "Contentment" stands out as significant. This suggests a scene where, despite the difficult circumstances of illness and the harsh realities of their lives, there was a sense of acceptance or peace among the individuals. Contentment can be understood as a form of resilience or inner peace found even in dire situations, reflecting perhaps a coping mechanism.
