He is Gu Chaoyang, the "sun" flying freely in front of others, but behind the scenes he is a prisoner trapped in the shadow of childhood and the black abyss. The wristband on the hand covers the scars of the past, and also locks in the morbid obsession with "White Moonlight".
She is Ruan Tingyu, a physics genius who broke into the hustle and bustle of the city from the silent countryside. She uses formulas to build the world, and her eyes are clear in black and white, unstained by dust.
An accident caused Ruan Tingyu to break Gu Chaoyang's embarrassment. Without comfort, she enlightened with cold physics: "Life is an orderly miracle going upstream in a universe of increasing entropy."
In the entropy-increasing universe destined to chaos, the scorching sun of depression and the rain of reason meet, and they work together to find the tiny but stubborn order that resists disorder, heals scars, and defines one's own existence. This is a profound youth story about how broken things "grow up" and how reason illuminates sensibility.
