Jiang Yan is dust, cowardly and stubborn, a gambler who has learned to make all-or-nothing decisions under the pressure of life.
Song Chenghao is a glimmer of light, dazzling and unruly, the only seemingly cynical genius willing to illuminate the dust.
Their encounter was a trivial fate stemming from the seating arrangements in the classroom.
Their entanglement has become the most profound "destiny" in each other's youth and destiny.
From the ignorant closeness of each other to warm each other in the first year of high school, to the sharp rupture between rumors and self-esteem;
From the distant separation caused by the great change of fate, to the sight of meeting again at the door of the adult world...
There is always a blurred line between them: they are confidants who cherish each other, and they are also secretly rivals; they are the only driftwood in a desperate situation, but they may also be the most painful thorns that pierce each other.
This is a relationship with a dangerous balance between "good" and "bad". It is the search for each other between dust and glimmer. It is the collision and symbiosis of two imperfect souls. It is a long story of seeing all the embarrassment and edge of each other, but still choosing to walk side by side towards the future.
