After the chaos at the amusement park, just when it seemed their relationship would deepen, the story takes the most heartbreaking turn in the series' history.

Below is a breakdown of the highlights and detailed plot summary for Episode 11 of "Mechanical Maid Mary."

Episode 11 "The Forgotten Mary" Plot Summary

After the amusement park incident, the physically and emotionally exhausted Mary and Arthur return to the mansion. However, fate has no intention of letting this pair rest, as they have an awkward "accidental encounter" in the bathroom. This sudden event, filled with the sweet-and-sour atmosphere of a romantic comedy, puts Mary's lie of pretending to be a robot at risk of being exposed at any moment.

Amidst the mix of blushing hearts and nervous tension, the plot takes a sharp turn. Arthur suddenly loses consciousness and collapses. Diagnosis reveals this is not mere exhaustion but an assassination attempt orchestrated by his stepbrother, Menard.

Fortunately, Arthur is not in mortal danger. However, when he opens his eyes again, though his body has recovered, he suffers a heartbreaking side effect—he has completely lost all memories of Mary.

Faced with a bewildered Arthur who politely says, "Hello, Mary," Mary is deeply shocked. The trust they built, their ambiguous interactions, and the unique gentleness Arthur showed toward "Robot Mary" all vanish in an instant.

Bathroom Showdown and Identity Crisis

The official preview images show their panicked expressions during the bathroom encounter. This is not just fan service but a key catalyst for advancing their relationship. For Mary, a human martial artist disguised as a robot, physical contact is always the biggest source of vulnerability.

Menard's Schemes Escalate

As the main antagonist, Arthur's stepbrother Menard's methods grow increasingly ruthless. From initial probing to now direct poisoning, it shows the family inheritance battle has reached a boiling point. This poisoning incident not only harms Arthur physically but also directly destroys his emotional connection with Mary.

The Heart-Wrenching Impact of "Nice to Meet You"

The most agonizing moment is undoubtedly Arthur's "Nice to meet you":

• Arthur originally despised humans but opened his heart only to "Robot Mary."
• After the memory reset, Mary must face Arthur's potentially resurfacing "human phobia" and cold personality.
• She must also rebuild their relationship without exposing her true identity.

This is undoubtedly the most difficult challenge Mary has ever faced.

Conclusion

Episode 11 of "Mechanical Maid Mary" will air this week. Will Arthur's memories return? How will Mary deal with this "most familiar stranger"? As the story approaches its finale, the outcome of this romantic comedy revolving around lies, schemes, and true feelings is breathlessly awaited.
