It tells a story about ideals, reality and lost love. The protagonist Chen Mo was once a young man with a musical dream, but after graduation he bowed to reality, entered a company, and lived a numb life overwhelmed by work. Chu Yan, his girlfriend who had been in love with him for many years, finally chose to leave because she couldn't bear the disappearance of the light in his eyes, and informed him of the upcoming marriage. This farewell forced Chen Mo to face the current situation of his own sinking and re-examine the youthful years that carried their common dreams. The story delicately depicts the struggle and loss of contemporary young people under the pressure of reality, as well as their deep regret for the "missed love" and the "city in the sky" that they have never reached.
Purpose: Under the pressure of ideals and reality, how can individuals avoid spiritual death and protect the unsinkable "city in the sky" in their hearts.
This idea is expressed through the carrier of "love tragedy", but its reference is far broader and deeper than love.
