A late-night live-stream accident catapults Marry into an unexpected media storm. After confessing her decade-long secret crush on her high school idol David while drunk, she finds herself not only emotionally exposed but also financially ruined by a $100,000 "accidental donation." Their paths collide again when David resurfaces as a popular game streamer, and their fates become irresistibly intertwined.
At a high school reunion, Marry struggles to maintain her composure under David’s intense gaze. The revelation that he never truly abandoned their shared past—a snowy night, a stray dog named Mimi—shatters her lingering resentment. But the shock deepens when David arrives at her gaming company as a brand ambassador, declaring cryptically, "I’m here for you."
As Marry uncovers David’s hidden longing for her, their relationship blossoms through dog-walking rituals and charged encounters. However, their fragile connection is tested at a wedding where David’s possessive act—a bridal carry and whispered confession—forces Marry to confront her insecurities. Just as happiness seems within reach, her manipulative ex-boyfriend emerges, threatening to unravel her carefully guarded truths.
When David reveals he’s known her identity all along—the username Little Marry giving her away—all pretenses crumble. In a moonlit car, their long-awaited kiss seals a promise, but shadows linger: Mimi’s mysterious origins and David’s fractured family history remain unresolved. As passion ignites, the final hangs heavy—will their love survive the secrets still buried in the past?
