The main character played by Pierre Deladonchamps, in my personal opinion, portrays forgiveness as depicted by director Kilian Riedhof, which I believe stems from media portrayal. In reality, when most people encounter a significant other due to a sudden traumatic event, they still need to face the remaining life themselves. Just like the male lead in the film, he has to face the responsibility of raising his child, and to be honest, even when he's alone, he still needs to sort out his thoughts. So, I think the director wanted to convey to those who are grieving that the things that make us sad, we can choose to either avoid them or muster the courage to invest ourselves in making our present better. That, in itself, is courage. We shouldn't worry about what others say about whether we've forgiven or moved on. I believe the main character's sister really played a significant role in helping him.
