Liu Run is an ordinary water delivery master, shuttling through the buildings of the city every day, yet always insisting on helping others warmly in his ordinary life. By a chance encounter, he helped Wang Xinxin, the president of the Wang family who had fallen into trouble. Facing crises coming thick and fast inside and outside the company, Liu Run relied on his extraordinary wisdom, calm ability, and strong sense of responsibility to resolve difficulties for her time and again. From business scheming to trust crises, he always responded calmly and never flinched. And in this process, Liu Run also rediscovered his own life value, no longer being that obscure water deliveryman, but a reliable partner who is seen and trusted.
