It appears you're referring to the character Gerasim from Leo Tolstoy's novella "The Death of Ivan Ilyich." Gerasim is a humble and compassionate young servant who cares for Ivan Ilyich during his illness. He stands in contrast to the other characters in the story who are primarily concerned with their own social status and appearances. Gerasim's simple, genuine, and empathetic nature makes him a memorable character in the novella.
As for whether Gerasim is realistically portrayed, it's important to note that realism in literature can be subjective and depends on the context of the story and the reader's perspective. In the context of "The Death of Ivan Ilyich," Gerasim's portrayal can be seen as a representation of the qualities of empathy and kindness that exist in some individuals. His character serves as a foil to the more superficial and self-centered behaviors of the upper-class characters.
Gerasim's portrayal could be considered realistic in the sense that there are certainly individuals who possess such qualities of genuine care and compassion in real life. However, it's also worth noting that characters in literature often represent specific themes, ideas, or contrasts that the author wishes to convey, and they might not necessarily be meant to represent the entirety of real human behavior.
Ultimately, whether Gerasim is realistically portrayed depends on one's interpretation and the standards of realism applied to the context of the story and the author's intentions.
