Kouki Harema leads a double life. To the world, he is an ordinary high school boy, but secretly he is Hikari, a popular fashion model who has taken the industry by storm and is hailed as the cutest girl in the world. This success, however, has given him an unusual and overconfident mindset: he no longer finds any girl his age cute because, in his eyes, none can compare to his own glamorous female persona.

This all changes when his unassuming and plain-looking classmate, Shizuku Amamiya, accidentally discovers his secret. Instead of the admiration or shock Kouki expects, Shizuku treats the revelation with surprising calm. For the first time, Kouki finds himself genuinely intrigued by a real girl. He soon makes a startling realization: he believes Shizuku Amamiya is actually cuter than he is. This confession throws the serious, low-confidence Shizuku into confusion, sparking an unusual competition and budding romance centered entirely on the concept of cuteness.

The story unfolds as a high school romantic comedy that pits Kouki’s diva-like confidence against Shizuku’s earnest sincerity. As their unlikely relationship develops, Kouki, who is used to admiration, must navigate genuine feelings for someone who doesn't fall for his charm, while Shizuku begins to see herself in a new light. The narrative follows their interactions as they grow closer, challenging Kouki’s vanity and helping him find value in authentic connection beyond the superficial world of modeling. The series spans three completed volumes.
