It is. The film is a Prime Video exclusive. If you have an Amazon Prime membership, you already have access. If you do not, you can sign up for a free trial. That is the short answer.
The longer answer involves regional pricing, device compatibility, and a few quirks I ran into. Here is everything I found, plus the full cast breakdown.

She is the first woman in 1,000 years to hold that title. She reportedly worked in an art gallery and a pub to pay for acting classes.
Lucas Barski as Vadim Arcadi. He plays the magnetic loner with a dark past. He is the main love interest.

The Plot and Ending: What Actually Happens?
I will keep this spoiler-light. But you should know what you are getting into.
Vadim is not just a brooding student. He is involved in something dangerous. He and his friend Félix work for a man named Oscar. Oscar does not let people walk away.
As Alma and Vadim grow closer, threats start appearing. Anonymous videos. Warnings. Someone wants to expose them.
The ending is not a fairy tale. Alma makes a choice to protect Vadim. It costs her their relationship. She leaves for Los Angeles. Vadim stays behind under legal restrictions. Their student film survives with both their names on it.
If you want a clean, happy resolution, this is not that film. The door is left open. But nobody rides off into the sunset.
The Honest Pros and Cons
What works. Vittoria Di Savoia carries the film. Her personal conflict feels real. The filmmaking scenes are genuinely interesting. The French campus setting looks great.
What does not. The chemistry is thin. One reviewer put it bluntly: the film "never makes you feel the love". The thriller subplot feels rushed. The supporting cast does not get enough screen time to make the family conflict land.
If you loved Maxton Hall or Culpables, this sits in the same genre. But it does not reach the same heights.
Who Should Watch It?
Watch it if you are a fan of Emma Green's books. You will want to see how the adaptation handles the source material.
Watch it if you like young adult romance with a suspense twist. The stalker element adds tension.
Skip it if you need strong romantic chemistry. The leads look good together, but the emotional connection feels underdeveloped.
Skip it if you want a complete story. The ending leaves threads hanging. A sequel is possible.
The Final Thoughts
You me against the world prime video is a straightforward watch. If you have Prime, open the app. Search the title. Press play. It costs nothing extra.
The film is a decent adaptation of a beloved book. It has a compelling lead performance and a beautiful setting. It also has pacing issues and a romance that does not quite spark.
Watch it for the book. Watch it for Vittoria Di Savoia's debut. Just do not expect a perfect love story.
