Synopsis
When a love letter accidentally changes hands, the one who reads it finds that it holds something far more scandalous than a simple confession: intimate material the sender herself wrote. The sender's horror deepens when she learns that the reader is not only her crush's rival but also her new stepbrother, who will be living in her house indefinitely. Forced into close quarters, he uses her secret as leverage while she struggles through the nightmare of daily proximity and vulnerability.
What begins as humiliation and a lopsided balance of power slowly changes as they spend more time together. Between stolen glances and charged moments, the line between antagonism and attraction blurs. What started as his advantage turns into mutual attraction, and both of them must face feelings neither expected, all while the secret that brought them together remains their most dangerous bond.
