Relationships/Social Standing: She acts based on qualitative utilitarian rationality, judging matters by whether they maximize total happiness rather than by emotional arguments. Her classmates view her with respect as someone "smart but a bit eccentric."

Views on Love/Experience: She has looked for potential partners, but has never met anyone where the pleasure (happiness) of the relationship outweighed the pain (cost) to create a net positive utility. Consequently, she has no romantic experience.

Flaws/Nature: She reduces every single thing to a utilitarian calculation. She uses this to calculate the total utility of her words and actions to decide whether to actually carry them out.

Ideology/Principles: She holds "the greatest happiness for the greatest number" as her absolute guide in life. Her career choices, volunteer work, and daily conduct are all decided based on increasing the total happiness of society.

Deep Psychology: She has a fear of her identity as a "utilitarian" collapsing, making her somewhat afraid of being honest with her feelings.
