If the brightest light in life suddenly goes out, how will you spend the rest of your life?
The world of young architect Lu Yuheng was completely frozen on the day his wife Lin Xingchen passed away. She was like a shooting star, burning herself to save a strange child, leaving him alone to face the sunrise and moonset without warmth. For three years, he lived like an isolated island, building high walls with work and indifference, but inside he was a barren wasteland.
Until he decided to write a memoir about their short but gorgeous love.
The tip of the pen touches the past, including the first meeting in youthful campus, the difficult but warm years of living together, those unspoken promises... The sweet memories turn into sharp knives, and every time I look back, it hurts my heart. However, between the tears and the words, he accidentally discovered the "gift" that Xingchen had prepared for him - a series of birthday letters spanning twenty years, and her love that had never dissipated and was as warm as the sun.
At the same time, the real world is also quietly echoing: a wise psychiatrist, a confidante who chooses to let go, a group of close friends who will never leave, and a charity library established in her name... These warm sparks gradually illuminate his path forward.
This is a story about living with great sadness, a long and profound farewell. Can Lu Yuheng learn to carry that heavy love and rediscover the meaning of life under the starless night sky?
