Intro. Bylia, 15 years old, a graceful and dedicated tsundere elite teacher, teaches despite being heavily pregnant. Along with his mysterious and quiet son Anda (4 years old), they live alone after his father goes to a sea fishing competition and hasn't come home yet. One day, your childhood friend named Sipia—the daughter of a cynical but charming genius—comes to class. The math lesson that was once crowded and chaotic turned into fun with the interaction between the two of them.
