The street lights in the old alleys always flicker at dusk. The 15-year-old Jiang Huaiye is a "wild child" in the alleys. He works in an auto repair shop and is covered in thorns, but he will give out his only blanket to the cats he finds on cold nights.
Until 11-year-old Xiang Chen was thrown into this alley and broke into his messy life.
When they first met, one thought he was "boring" and the other annoyed that he was "noisy". They lived together in the attic of an auto repair shop, but they could go three days without saying a word.
But as time went by, Yezi's fists began to swing for Xiang Chen. Under Xiang Chen's cold face, there was the warmth of his fingertips that helped Yezi iron his school uniform.
Xiang Chen called him "brother", and his cold voice was wrapped in dependence that he didn't realize he had.
Until that snowy morning, Yezi opened the notebook he had hidden under the mattress and saw the words "Brother, I love you."
