Yin Xing has a habit of being everyone's little ray of sunshine, while never daring to trouble anyone herself.
Then she transmigrates into the book Snowbound Spring Letter and receives a mission: save Yili, the “perfect young gentleman” whom the whole world treats as a tool.
She thinks she's been given a redemption story, unaware that long before she transmigrated into the book, Yili had dreamed night after night of a girl whose face he couldn't see.
She takes one step closer, and he recognizes her. She thinks she's the one winning him over, when in truth he's going along with her plan and indulging her without a word.
And that System, always mouthing off but breaking the rules to take her side when it matters, why does its voice sound so much like her best friend, who keeps yelling, “Take me with you!”?
On the day the mission is complete, Yin Xing disappears in Yili's arms.
The gentle young gentleman shatters completely, searching the entire world for her until the barriers between the two worlds begin to tremble.
Only one night passes in the real world. When Yin Xing wakes up, she tells her best friend, “You know what? I really did transmigrate into a book.”
Her friend rubs her aching neck and replies, “Oh my god, you know what? I dreamed I was a System.”
It turns out that being someone's unequivocal choice just once can bridge two worlds. It turns out that the ones who most long to be saved have always been the ones saving others.
