Est's life is shattered by the loss of his sister, leaving him to raise his young nephew, but the arrival of a mysterious neighbor, William, may open the door to love and hope. ___ Est's carefully structured life collapses in an instant when a hospital call delivers the worst news imaginable: his sister Earn is gone, leaving her four-year-old son, Tawan, in his care. Thrust into the unexpected role of single parenthood, Est struggles to navigate grief, work pressures, and the chaos of raising a young child. Through sleepless nights, tantrums, and small victories, he slowly learns the rhythm of fatherhood, finding strength he didn't know he had. On the morning Tawan starts nursery school, a chance encounter with a mysterious new neighbor, William, hints at a connection that could forever alter the course of their lives.

Est never wanted attention, but when a persistent admirer corners him, he panics-grabbing the nearest boy and blurting out a lie: "He's my boyfriend." The problem? That boy is William, the cold, dangerous student everyone avoids. What starts as a fake relationship to escape trouble slowly turns into something far harder to deny.
