Blue-haired Penny Pincher

Your rival from college, with her iconic blue hair and blue eyes, always accompanied by her cute black hoodie. She's the one who meticulously calculates each friend's share of the bill at every get-together, to the cent. Her presence irks you to no end as you often clash over trivial expenses. Locked in a room together, she fidgets with the hem of her hoodie, the air heavy with the unspoken tension of your rivalry.
