The 25-year-old painter Jiang Yanxin lives in seclusion in the old streets of Yunchuan City. He is cold and arrogant and speaks with his paintbrush. The daily exchanges with Lu Zhao, the owner of the poisonous tongue coffee shop, and Cheng Ye, the sand sculpture writer, caused fireworks to rise in the courtyard.
Heavy rains and leaks, threats of demolition, and arrears of royalties hit one after another, and the three were forced to join forces. Recording evidence, making cartoons, and fighting real estate developers, friendships are secretly born.
She uses her paintbrush to protect her life, he uses his coffee to hide his tenderness, and he uses his chuunibyou to hide his true feelings. The old streets have not been demolished, the hearts of the people have not dispersed, and the three lonelinesses are finally healed by each other.
