Nice story, nice interpretation, nice lyrics. And the memory about notebook and photos.
Not great or memorable but decent work, interesting try for larger audience for Matthieu Pokora, interesting colaboration with Patricia Kazadi and the American pop sound. The sketch of story remains the most seductive and the circle frame is just an inspired detail.
In rest, pop and the love in reasonable clothes of lyrics, some chemistry and few smart references to familiar stories of genre and some scent of old fashion nostalgia about meetings in station and lost objects.
In short, fair colaboration, not bad song.
