Six people are reunited for a class reunion, and time has left completely different marks on them: Lin Yujia (the female protagonist) has become a high school art teacher, while Wang Weiyi (the male protagonist) has become a top expert in the field of carbon fiber abroad. At this moment, he should be recalled to the country to devote himself to the research and development of the next generation of the domestic commercial aircraft C919. Song Zeyu (psychological counselor), Zhang Chi (police officer), Xun Wenruo (finance), and Shen Xulu (university professor) have all been forged by time into distinct but intertwined existences in their respective fields over the past ten years.
As the group of six interacted more and more, fragments of the past continued to emerge, including the geological hammer pendant on Lin Yujia's chest, the yellowed exploration log Wang Weiyi accidentally dug out of his father's safe, the scrawled signatures on old photos. Lin Yujia always struggled between closeness and alienation when facing Wang Weiyi... She used colors and lines to build a world for the students' hearts, but in her own world, there was a blank space that could not be filled, a shadow that could not be dispelled...
Noticing the subtle alienation between the two, Song Zeyu made suggestions as a psychological counselor. Lin Yujia and Wang Weiyi then began psychological counseling respectively. Under the professional companionship and guidance of the counselor, Lin Yujia finally dared to reveal the dusty secret, and Wang Weiyi, with the rigor and empathy unique to scientific researchers, looked back on the mistakes of his fathers and faced the bond between the two generations. When the news of the successful first flight of the next-generation C919 aircraft came, they also untied their knots in understanding and forgiveness, making love like carbon fiber that has been tested tens of millions of times, with both the strength to support each other and the toughness of tender dependence.
