A sudden terminal illness fell like silent snow in the depths of winter, burying every bright promise between Lin Yan and Su Wan. From the colors spreading across the snow at their first meeting, to the profile she secretly sketched in the library, and the dreams of seeing the aurora they shared on the rooftop, their love had once been filled with the warmth of youth. But as his life entered its final countdown, Lin Yan chose the clumsiest way to push away the person he loved most: "I don't love you anymore." Behind that lie were his reddening ears, which he couldn't hide, and the increasingly messy words of longing in his diary.
Su Wan left for a distant land with a broken heart. Alone on Norway's snowy plains, she gazed up at the aurora, unaware that the person who had once promised to go with her was slowly forgetting what she looked like in his hospital bed. It wasn't until the long-delayed email arrived three years later that the truth behind all the silence came to light. Snow fell and melted again. The name on the gravestone and the paintings in the studio both became promises left unfulfilled. Some loves are destined to last only through the depths of winter, like a magnificent yet fleeting aurora that once lit up their lives before fading into eternal silence.
