The song "Celui Que J'aime" by Joyce Jonathan tells the story of a relationship that wasn't meant to be. The lyrics reflect on the fact that despite their differences, the two individuals involved in the relationship loved each other. However, they realized that they were not compatible and that there was nothing that could make their relationship work. The singer sees her former partner happy with someone else, and it brings a smile to her face. She has moved on and found happiness with someone new, and they have blossomed together. The chorus emphasizes the singer's contentment with herself and her ability to say "I love you" to those who matter to her, including the person she loves. The relationship between the two was like a train journey. They moved forward together, but there were no beautiful moments or a connection that could be seen in their photographs. The singer acknowledges that love is visible on people's faces, but in their case, they were not a beautiful couple. Overall, the song speaks about personal growth, self-love, and being able to say "I love you" to the person who truly deserves it. It reflects on the acceptance of the past and the ability to move on while finding happiness within oneself.
