This short film is the second part of Truffaut's famous "Antoine series", which is included in the album "Love at the age of 20". 17-year-old Antoine Doinel (Jean-Pierre L é aud Jean-Pierre Leo) fell in love with the girl Colette (Marie-France Pisier) at first sight and made a series of "warm-up preparations". He plucked up the courage to chat her up, and then the two often met to chat, drink coffee and go to concerts. Antoine thought that Colette was also in love with him and made an almost crazy move to pursue him more passionately, but Colette already had a boyfriend and only regarded him as a friend.
