Haruki and Mai are the names of the two key characters who drive the plot of the narrative. Haruki is a reserved person who does not want to draw attention to himself and would rather keep to himself than interact with others. At this stage, he is more of a spectator than a participant in the action. However, don't judge a person by their outward demeanour since he really has a high level of intelligence. Mai is comparable in certain ways. She is also quite shy and has the propensity to keep to herself, despite the fact that Haruki shows interest in her, the only thing on her mind is how she can avoid interaction with him.
