Mina Hibino, Sanae Tsukimoto, and Yukari Tenkawa transform ordinary school days into a vibrant blend of hyperactive energy, deadpan teasing, and hopeless romantic daydreams. At the center is Mina, whose pure energy, expressive thick eyebrows, and unfiltered love for fun constantly drag her friends into goofy antics and dramatic reactions. Countering this whirlwind is Sanae, whose unbothered, deadpan exterior and tomboyish spirit mask a fiercely loyal heart, often expressing affection through stoic teasing and playful cheek-pinching. Trying to anchor them all is Yukari, the level-headed voice of reason who hides a passionate fascination with mature romance beneath her neat glasses, frequently scolding the others for slacking off on homework only to end up lending them her notes anyway.
