Official story outline
Ethan used a model’s photo to find love online. When his gorgeous girlfriend wanted to meet, he panicked—and ghosted her. Six months later, he visits his best friend’s home. The older sister coming downstairs? His online ex. And she’s a ruthless mafia boss who hasn’t gotten over him. She’s never seen his real face. But she knows his voice. Ethan just needs to keep his secret and survive the visit. Then an innocent delivery brings him to her private docks. He turns to leave. She grabs his arm.
ShortDramaBuzz treats the listing synopsis as a dated source snapshot. When the official text is truncated, we stop at what is written rather than filling gaps from unofficial recaps.
Episodes and length
The official ShortMax record currently lists 25 episodes and about 44.1K public views (snapshot reviewed Nov 9, 2026). Overseas short-drama episodes are typically about one to three minutes each; that is an industry pattern, not a measured runtime for every episode of this title.
We do not republish a per-episode title list. Open the official listing for the live episode rail, unlock state, and any newly added chapters.

What the tags signal
- A concealed identity creates a second layer to the plot: watch how other characters behave before they know the truth.
- Family loyalty, protection, and danger are intertwined, making trust a practical risk rather than only an emotional one.
Tags can overlap, so they describe conflict style more than quality or ending.
Dark Romance themes around this title
Dark romance explores attraction in situations shaped by danger, obsession, unequal power, or moral compromise. The label signals heightened material, not a guarantee that every action is endorsed by the story.
Check the official premise and other tags before watching. Mafia, forced proximity, toxic romance, and revenge can produce very different experiences even when the visual tone is similar.
Family Drama themes around this title
Family dramas turn private history into present-day conflict. Lost children, inheritance disputes, parental favoritism, and chosen-family bonds can all reshape who belongs at the table.
The compressed format rewards stories with a strong central relationship. Look beyond the number of twists to see whether relatives have distinct motives rather than serving as obstacles only.
Hidden Identity themes around this title
Hidden-identity stories create two simultaneous plots: what the other characters believe and what the audience already knows. The concealed self may be a billionaire, heir, fighter, doctor, royal, or long-lost relative, and every insult adds pressure to the eventual reveal.
A good reveal changes relationships instead of simply ending the story. Compare titles here by the secret being protected and the reason disclosure is dangerous.
How to use this guide
Use the facts box for episode count, platform, and the official call to action. Use the outline for the premise the rights holder already published. Use genre links when you want adjacent titles with verified listings. Skip unofficial “ending explained” posts if you want to experience the series as released.
ShortDramaBuzz will not fabricate a cast list, episode-by-episode titles, or a completion status we cannot see in the structured listing. If the official app later expands the synopsis or changes monetization, those updates belong on ShortMax first; our source-reviewed timestamp shows when this snapshot was last checked.
