Meng Hechuan, a brilliant aerospace scientist, encounters a beautiful woman at the train station whom he suspects of being an enemy agent. This “swallow” clings to him, calling him “Brother” and pleading for his help.  To prevent the enemy from stealing vital information, Meng Hechuan takes the woman with him on the train, intending to interrogate her. However, he discovers she is a gifted translator.

Forced to bring her to the aerospace team, Meng Hechuan finds himself constantly surrounded by her, both during the day and in his dreams.  His usual stoicism crumbles as he falls for the captivating woman.

Meanwhile, Bai Yan, a transmigrated soul, is determined to avoid the fate of the original character, a cannon fodder love rival.  She shuns Meng Hechuan, the villain in the book, and sets her sights on a new life.  But when she tries to move on, Meng Hechuan blocks her path, his eyes burning with desire.  “You started this fire, now don’t blame me for igniting your heart.”
