Zhao Yiman is a person who has no ideals, no emotions, no money, and only specializes in soy sauce. I have always believed that friendship is the most important thing, but sometimes I feel lonely in real life - friends and relatives who are reluctant to leave each other over wine and dinner, old friends who have become likes in WeChat holiday group messages overnight, video calls, WeChat red envelopes, and Alipay transfers allow people thousands of miles apart to feel the warmth between each other, but I still feel sour in my heart when I put down my mobile phone and face someone's hot pot. Maybe because of loneliness, maybe because of liking, I started to care about everything about him, searching for his related social accounts, and paying attention to his every status. But I was afraid of being sentimental, so I refused to push him away, pretending to be indifferent, pretending to be free and easy, but in fact, only I know the warmth and coldness.
