Plot Summary: A Novelist's Unexpected Muse

Kei is a talented novelist with a major problem: he has zero dating experience. Yet his publisher has just assigned him his most challenging project yet—writing a BL (Boys' Love) story. How can a romance writer craft authentic emotional depth without understanding love firsthand?

Enter Kairi, Kei's sharp-tongued and devilish stepbrother, who seems to have all the romantic experience Kei lacks. In a turn of events that's equal parts awkward and endearing, Kei finds himself turning to his younger brother for guidance. As Kairi teaches him about love and those unmistakable "heart-pounding feelings," the line between research and reality begins to blur. 📚
