A young boy and an unsuccessful zipper spirit become frustrated with their home life and decide to leave home together. The young boy's little sister tags along for the adventure, but what awaits them ahead?

Smart, refined, and strikingly gorgeous, half-Russian half-Japanese Alisa Mikhailovna Kujou is considered the idol of her school. With her long silver hair, mesmerizing blue eyes, and exceptionally fair skin, she has captured the hearts of countless male students while being highly admired by all others. Even so, due to her seemingly unapproachable persona, everyone remains wary around the near-flawless girl. One of the few exceptions is Alisa's benchmate Masachika Kuze, a relatively average boy who spends his days watching anime and playing gacha games. Despite his nonchalant demeanor, Masachika is the sole student to receive Alisa's attention. Unable to be fully honest, Alisa is frequently harsh on Masachika and only expresses her affection in Russian. Unbeknownst to her, however, Masachika actually understands the language yet simply pretends otherwise for his own amusement. As the odd pair continues to exchange witty and playful remarks, their relationship gradually grows more romantic and delightful—and Alisa might finally learn to freely convey her true feelings.

Tired of being looked down upon for her unattractive appearance, middle schooler Lim Jugyeong turns to the transformative powers of makeup. First, she experiments with BB cream, lip tint, and eyeliner; then she begins using mascara, double eyelid glue, and colored contacts. Before she knows it, Jugyeong goes from being a girl who is bullied for her ugliness to being praised as a high-class beauty. Constantly surrounded by those who adore her goddess-like appearance, Jugyeong can now live a more than comfortable life at school—she simply has to keep her bare face a secret. However, everything changes when the new transfer student, Lee Suho, enters her life. Not only does the handsome Suho become immediately popular among their peers, but in a chance encounter, he also becomes the only classmate of Jugyeong's to see her face beneath the makeup. With her reputation on the line, Jugyeong must do whatever it takes to hide the truth about her appearance from the rest of her classmates. But the more time she spends with Suho, the more Jugyeong finds herself questioning whether one's true beauty lies solely in their looks.
