Xu Youyou rebirthed to when she was 16 years old and chose a path different from her previous life and met Qiao Mu ten years earlier. The youth who had braved the wind and snow protecting her till death — and who had confessed to her.

And she realized, the Qiao Mu ten years earlier and the Qiao Mu she knew were completely different people. He didn’t have his smile that could radiate sunlight, he didn’t have his courage that could penetrate snowstorms, and he certainly didn’t have his perfect eight pack. He was like a short mushroom, quietly growing in the corner’s shadow.

A widely known reckless and fearless girl, who was the complete opposite of him. She was good at everything, except things relating to love. Clearly he wasn’t her type, yet she always provoked him. But the biggest joke was himself, he clearly knew everything, yet could not help but fall into the hands of the enemy.
