I was catching the bus in the rain when I received a call from my sister-in-law Su Wan. When his brother Lin Chen was on a business trip, Su Wan said that the water pipe at home was broken and he was afraid of something happening, so he asked him to stay overnight. Lin Mo hesitated for a moment and agreed. When he stepped into his sister-in-law's house, under the warm yellow light, Su Wan's reddish eyes and the warm porridge on the table gave the rainy night a subtle warmth.
