As Jonas continues to write his love letter, he starts to reflect on his past relationships and how they have impacted his life. He remembers his first love, his high school sweetheart who broke his heart, and his failed marriage that left him feeling empty and lost.
Throughout the day, Jonas interacts with various patrons at the café who share their own stories of love and heartbreak. From a young couple experiencing the excitement of new love to an older couple rediscovering their spark after years of marriage, each encounter provides Jonas with a different perspective on love and relationships.
As the day progresses, Jonas begins to realize that his feelings for Léa were not based on true love, but rather a sense of nostalgia and comfort. He comes to understand that he needs to let go of the past and embrace the uncertainties of the future.
In a surprising twist, Léa shows up at the café towards the end of the day. Jonas finally musters up the courage to read her the love letter he wrote, but instead of asking for her back, he thanks her for helping him see the truth about his feelings and giving him the closure he needed to move on.
The movie ends with Jonas walking out of the café, feeling a sense of freedom and optimism for what the future holds. He realizes that love comes in many forms and that true happiness can only be found within oneself.
