This novel mainly follows Xiao Jing's growth. Events in high school lead her to take up smoking, drinking, and fighting, and to spend every day in a daze. Just when Xiao Jing thinks she will keep sinking into this state, she finds a ray of light at the edge of the abyss. She meets Meng Yu, who has liked her since middle school, has always been influenced by her, and has illuminated her life. Meng Yu gives her hope.
So rather than saying one of them saved the other, it's more accurate to say they saved each other. They protect each other and grow together, becoming each other's light! But good times don't last. For many reasons, they part ways. On the surface, both their lives eventually return to normal. Yet, by a twist of fate, they are brought from their separate places to the same city. Perhaps their fates were intertwined from the start, and they were destined to remain tangled up in each other's lives... When they meet again, everything that happened between them back then begins to come to light. Will they regret the choices they made? What choices will they make when they meet again? Will they regain what they lost, or repeat the same mistakes...
