Mona's Worst Enemy: the stepbrother rivalry series on Candy AI

Enemies under one roof

Mona likes her life organized, and David is the last person she would choose to live with. The official synopsis forces the two stepsiblings into the same house and lets the friction do the rest: a daily contest of wits, stubbornness and bad decisions. The series is a slow enemies-to-something-else story, and the title makes the joke explicit: the enemy in question is the one person she cannot move out from.

Mona Newman and David

The lead is Mona Newman, a Candy.ai character with her own chat profile on the platform, and the candyshorts.com address files the series under her name, /series/mona-newman. She also leads a second public series, Mona's Obsession, so she carries two titles in the public catalog. David, the stepbrother, is written as her opposite, a confident type she looks down on. No creator twin is involved.

Fifteen episodes with dubbed audio

The series still had 15 episodes in October 2026. Its free episodes are on the long side, 86 and 78 seconds, which gives the rivalry almost three minutes to take shape before the paywall. It is one of 14 public series with dubbed audio, in French, German, Spanish, Italian and Portuguese, with subtitles on top. On Candy.ai its page has the numeric address /series/11.

Paid episodes

Thirteen episodes, from the third to the fifteenth, sit behind Premium, and each one takes tokens from the plan's allowance. With the setup done in the free pair, the paid part is where the rivalry develops. Viewers who enjoy slow-burn rivalries have plenty to watch here, and the dubbed tracks carry over to the paid episodes. The plan prices are listed in the free guide.

Content notes

Mona's Worst Enemy sits at level 3, Moderate, on our scale. The paid episodes show nudity and sex scenes, yet the rivalry keeps most of the runtime. The Stepsister and Taboo tags describe the household, not the level. Among the 15-episode titles, it shares level 3 with Simona Rossi: Wrong But Right, while Caught Between Sisters sits at level 4 with the much longer YES MA'AM, as the nudity guide shows.

Where it plays

The Candy.ai page is candy.ai/candy-shorts/series/11, and candyshorts.com lists the series under /series/mona-newman rather than under its title. The button above takes you to the Candy.ai page. Mona's other public series, Mona's Obsession, and a Spicy title with her name, Mona: My Wild Step-Sister, are part of the same catalog, and her chat profile on candy.ai sits under mona-newman.

Our take

On its synopsis, Mona's Worst Enemy is the lightest of the long titles we rate: a rivalry played for sparks rather than for betrayal, with a lead whose personality comes through in each argument. The dubbed audio makes it one of the more accessible series for viewers outside the English-speaking world. It will suit viewers who like the build-up more than the payoff, and anyone who already chats with Mona on Candy.ai.
