My Girlfriend’s Little Sister Moved In is a five-episode series on Candy Shorts, the short-form video section of CandyAI. The premise is domestic and quietly loaded: his girlfriend’s younger sister, a competitive gymnast, moves into the flat for a month to train ahead of the biggest competition of her career. Every morning, while the girlfriend is at work, she stretches in her room. He notices. She has noticed him noticing, and, as the synopsis puts it, she likes it. That is the entire engine of the series: a shared apartment, a daily routine, a look that lasts a beat too long, and a houseguest who is in no hurry to close her door.

How to Watch My Girlfriend’s Little Sister Moved In: Free and Premium Episodes

Like the rest of the Candy Shorts catalogue, the series is divided between free and premium episodes. The first two are open to anyone with a CandyAI account, and they establish the arrangement: the sister’s arrival, the training schedule, the empty flat on weekday mornings and the first unspoken exchange between the two of them. Episodes three, four and five are premium, and that is where the month-long stay starts to have consequences. The split functions as a sampler. If the slow build of the first two episodes appeals, the premium half continues in the same register, with the stakes raised.

Episodes are brief, a couple of minutes apiece, so each one is a scene rather than a chapter. The series makes a virtue of that by anchoring every instalment to the same morning routine: the girlfriend leaves, the sister begins her stretches, and the episode follows one variation on what happens next. Because the routine is restated every time, the five parts read as a clear progression in order, and still make sense if you drop in halfway.

The Cast of My Girlfriend’s Little Sister Moved In

The sister is played by Lea Fontaine, one of the Candy characters the platform builds its series around, and she is the focal point of every episode. The girlfriend is mainly an absence, a reason the flat is empty on weekday mornings, and the boyfriend is the viewer’s own point of view, so the camera stays with Lea Fontaine for most of the run. The series keeps her consistent in look and manner across all five episodes, which is what lets the small escalations register: a glance returned in episode three means something because it is the same woman who did not return it in episode one. The gymnast framing also gives her a physical vocabulary that the series uses to tell its story without much dialogue.

How My Girlfriend’s Little Sister Moved In Is Made

Nothing here was filmed. Every frame is generated through CandyAI’s pipeline, and the recurring character is held consistent across the run so that the houseguest in the finale is unmistakably the one who arrived with her bags in the opener. The look is smooth and stylised, more in line with polished animation than with live-action video, and the pacing is designed for short, self-contained scenes. The single-location setting works in the format’s favour: one flat, one room, one recurring morning light, all rendered consistently from episode to episode, which is precisely the kind of continuity that distinguishes a series from a string of clips.

Where to Stream My Girlfriend’s Little Sister Moved In

Starting is easy. A free CandyAI account unlocks the first two episodes, and the CandyAI apps for iOS and Android are the natural way to watch something this short on a phone. Premium membership unlocks episodes three to five and the rest of the gated catalogue with them.

This is adult content, available only to users aged eighteen and over. On those terms, My Girlfriend’s Little Sister Moved In is a well-judged, slow-burn entry in the Candy Shorts line-up: one recurring lead, one domestic routine, and five short episodes that let a month in a shared flat run its course.
