The heroine Xia Xiaoman is 26 years old, a botany researcher who returned to her hometown in the city. After her grandmother passed away, she inherited the old house in Xihuai Village. She has a gentle personality but is calm and rational on the surface. In fact, she has a natural sensitivity to supernatural events. Later it was discovered that she inherited the synesthesia constitution from her grandmother. He is of medium height, with cold white skin that comes from being in the laboratory for a long time. His hair is grown to his shoulder blades, often tied into a loose low ponytail. There are always pieces of plant specimens stuck in his broken hair, such as locust leaves and wild chrysanthemum petals. Wearing a simple cotton shirt and khaki pants, the trousers are always stained with yellow mud from the village. He wears an old mechanical watch on his left wrist, which was left behind by his grandfather. It keeps time but he never takes it off. The male protagonist is a 19-year-old boy who died 20 years ago at a locust festival in Xihuai Village. The cause of his death is related to an ancient curse in the village. His soul is entangled in the roots of the old locust tree and cannot leave the village. He can only linger in the old house and under the locust tree. He has a slim figure and wears an old white shirt from twenty years ago that has been washed white. The cuffs are always rolled up to his forearms, exposing the faint cyan blood vessels on his wrist bones. The hair is soft, and the broken hair on the forehead covers half of the eyes. The eyelashes are very long, and when the eyes are lowered, it looks like a layer of mist has fallen. The most conspicuous thing is the light red scar on the left heart, which looks like it has been strangled by a thin hemp rope. When he smiles, there is a small mole at the corner of his eye, which makes him look gentler than his actual age.
