Don’t Worry, I’m Fine

Lili returns from vacation to a quiet house and discovers her twin Loïc has left after a violent argument with their father. The close bond between the siblings makes the departure feel like a rupture in the family. She immediately fears something terrible has happened and begins to search for him.

With no word from Loïc, Lili's worry deepens as she loses touch with the world she shared with him. The absence seems to swallow her routine and hope alike, and she clings to any clue that might explain his disappearance.

Lili stops eating and grows weaker, and is hospitalized where doctors treat her physical decline. In the hospital, she appears to have decided to stop living, overwhelmed by grief and the fear of losing her brother completely. The hospital environment amplifies her sense of isolation as she teeters on the edge.

A letter arrives from Loïc in which he apologizes for leaving without a word and insists he won't be coming back. He explains that he has been traveling, taking petty jobs, and he blames their father for the life he's led. The letter offers a fragile thread of connection but confirms that Loïc is not returning.

Lili gradually recovers and, together with Thomas, Lea's boyfriend, begins to trace the trail of letters and clues Loïc left behind. They move through small clues, visit places he mentioned, and piece together his movements.

As they spend time together during the search, Lili and Thomas develop a growing affection for one another. Their collaboration deepens their bond while they chase elusive leads about Loïc. The budding romance is intertwined with the emotional weight of the case.

On a trip to Saint-Aubin with Thomas, Lili notices her father mailing letters and starts to suspect he is imitating Loïc's handwriting to protect her. Her suspicion grows as she watches the routine mailings and compares the handwriting to Loïc's known letters. The trip hints at a deeper family secrecy.

While visiting his grandmother's grave, Thomas discovers Loïc's gravestone, signaling that Loïc had died rather than vanished. This moment makes the mystery concrete for him and shifts the trajectory of their quest. He begins to realize the truth may be heavier than they imagined.

At a family lunch, Thomas speaks with Lili's parents and learns they know more about Loïc's fate. They reveal that he died in an accident during mountain climbing and urge him not to tell Lili. Thomas is skeptical of their secrecy but is drawn into their version of events.

Lili returns home and discovers Loïc's guitar hidden in her father's car, a sign that he could not have left behind on his own. The guitar acts as a tangible link to Loïc that contradicts the idea of a voluntary departure. The revelation deepens the sense that someone else is keeping Loïc's memory alive.

Even though they know the truth about Loïc, Lili and Thomas choose not to discuss it aloud and continue living with its impact. They carry the knowledge privately while maintaining their relationship. The silence becomes a shared pact in the face of unresolved questions.

They talk about leaving the city and going to the sea, signaling a new beginning together after a year of searching and heartbreak. The plan embodies hope and a possible future beyond the shadows of Loïc's fate. It marks the transition from revelation to shared resolve.
