Yun Shu, 28 years old, is a senior designer at a major Internet company. When he received an annual salary of 600,000 yuan, he chose to resign and hid in the Tonglu Mountains to open a studio. It wasn't that he was emotionally hurt, or that he longed for poetry and the distance. It was just that one day he suddenly discovered that every interface he designed was inducing users to over-consumption. Yang Xi, 27 years old, is a pediatrician at the Children's Hospital. She always has a sketch that Yun Shu drew for her in her senior year of high school on her phone, although it is so worn that her facial features cannot be clearly seen. Ten years later, one rainy night, she opened the door of the studio called "Invisible". This is not a story of reunion, but a story of two souls who have been polished by life and get to know themselves and each other again in the mountains and wilderness. If the mountains don't see me, I will go and see the mountains. If people miss me, they will come over the mountains.
