Lin Ye, a veteran, came to Jiangcheng from the countryside with his skills and desire for "home". When he was hungry and cold, he was taken in by Su Qingzhi, the proprietress of "Qingzhi Teahouse". Although Su Qingzhi is 32 years old, her natural charm is comparable to that of an international supermodel. Under her gentle and elegant appearance, she hides the tenacity to support the teahouse alone and face the troubles in the market. Lin Ye stayed as a helper, while adapting to the daily fireworks of the teahouse - learning to make tea, sorting tea leaves, and accompanying Su Qingzhi to purchase, while silently shouldering the responsibility of protection: from driving away gangsters who asked for protection fees, to dealing with malicious sabotage against the teahouse, to resolving the secret crisis left by Su Qingzhi's past. The story has no end. In the slow time in the old alleys of Jiangcheng, Lin Ye guarded Su Qingzhi's tenderness with the calmness of a soldier. The two gradually became dependent on each other in the trivial daily life and sudden troubles, and they constantly met new people and things, making the teahouse a "safe haven" with warmth and strength.
