This book unfolds with two main lines of Lin Qian and Su Yi'an. Under the multiple backgrounds of the workplace, a foreign country, and family relationships, Lin Qian studied in France, and Su Yi'an became an international exchange student. Their emotions deepened through separation, misunderstanding, and growth. The entrepreneurial paths of Cheng Yige and Qin Ran connect urban struggle and romantic emotions, while the stories of Irene and Yu Huasen serve as a contrasting line to show different views on love. Multi-line stories are intertwined, gradually advancing the character's self-understanding and emotional choices. The book is divided into ten volumes, unfolding in a fast-paced manner: multiple lines are laid out in the early stage, relationships are budding, climax conflicts and career breakthroughs are in the middle stage, emotional choices, growth and healing are in the later stage, and finally it ends with the successful conclusion of each main line.
