At first glance, Yeon Skylar is a model student, with his excellent academic performance, an award-winning photography club career, and considerate disposition. Despite it all, he is somewhat introverted, and his only real friend is Seong Chan-il, a friendly, outgoing classmate. For a year already, Skylar has been hiding his crush on Chan-il—and especially his extensive collection of all the candid photographs of Chan-il he has taken in secret.

Skylar's peculiar hobby is discovered by Baek Cirrus—Chan-il's seemingly kind and sociable friend. Cirrus promises not to expose Skylar's secret, but Skylar's anxiety deepens with everything Cirrus does. His words always carry double meanings, and his teasing is always a breath away from confessing everything to Chan-il. A tense game of blackmail, emotional control, and shifting power arises between Skylar and Cirrus, two broken teenagers who fear one another, the world, and the consuming intensity of a love neither expected.
