Yu Wen is a young lady who has no worries about food and clothing, while An Yichen is an "orphan" who started from scratch.
The two met after An Yichen's accidental rear-end collision, and Yu Wen fell in love with this handsome but cold-looking man.
Faced with Yu Wen's fiery love, An Yichen was moved, but he did not dare to respond because of family illness. An Yichen was afraid that at the end of his life, Yu Wen would be left alone to face those memories of the past, and she would be miserable. So An Yichen chose to escape, hoping that all this would not start. An Yichen felt that in that way, Yu Wen might be able to spend her life happily.
An Yichen silently guarded Yu Wen and helped her solve one problem after another, but Yu Wen still couldn't understand An Yichen's deep affection. Later, when Yu Wen knew everything, the development of things was irreversible.
At the end of the story, Yu Wen gradually loses her warmth in An Yichen's arms. An Yichen desperately wants to remember her warmth, because that is the last trace of warmth left by Yu Wen to him.
