How to interpret Chrysler's love joy and love sadness

Joy of Love and Sadness of Love are two lyric sketches created by Chrysler, which mainly describe the sensitive, complex and changeable emotional state of boys and girls. Seven or eight points of joy in love is joy, but joy actually contains a little bit of anxiety and a little bit of sadness. The sadness of love is actually accompanied by a little bit of sweetness in the little sadness of seven or eight points. These two songs describe the sensitive and sentimental mentality of young people. If you have read Goethe's young werther, it is easy to grasp the emotional characteristics of these two love songs. Victor is sometimes ecstatic and sometimes sad, which is the usual attitude of young people in the face of personal small emotions. A little young people insist on worrying about new words.
