I think Paul Kircher really captures the vulnerability of his "Lucas" character well here. He lives with his parents - Juliet Binoche and Christophe Honoré until an accident robs them of his father. His brother "Quentin" (Vincent Lacoste) returns from his home in Paris and the family start to come to terms with their grief. That manifests itself in many ways amongst the threesome, and causes friction between them too. It's his brother who comes up with the idea of taking the seventeen year old "Lucas" for some time in the big city, and so off they go. He shares his small apartment with "Lilio" (Erwan Kepoa Falé) to whom the young man immediately takes a shine. We already know that he is gay, and his time in the city gives him chance to explore the cultural sites of the city, and to give his Grindr a bit of exercise too. The narrative is peppered with occasional flashbacks as the young man continues to struggle to come to terms with his loss, becomes increasingly more selfish and introspective; reckless and thoughtless and also a little unforgiving of the stress on his family too. A bit of a misdemeanour (for a measly 150 Euros) sees his brother send him back home and that's where things step up a gear and everyone gets a fright. Reality takes the family by the scruff of the neck - but hopefully it will start the young "Lucas" on some sort of path to continue his life more positively. Binoche features sparingly, but her every expression conveys emotion - whether that be sadness, grief, exasperation or love; and there is plenty of love amongst this family. Lacoste also fares well as "Quentin" must reconcile the needs of his own life with those of his family - not an easy task when your teenage brother has the hots for a flatmate ten years older. It's Kircher who steals this, though. There is a confidence about his performance that is engaging to watch. He does elicit sympathy but you do want to just give him a slap at times, too. His behaviour isn't malevolent, but it's not so much of a melodramatic "cry for help", either. It's about his sorrow, his sadness and all of their emptiness, and the bitterness of those feelings. Who knew people still wore turquoise underpants, either! Maybe a little on the long side, but I reckon this actor might be around for a while to come.
