After graduating from college, Gu Heng became a humanoid master. He loved making dolls, so he left his hometown and came to a different city to set up a doll-making classroom. His half-sister Shen Xi came to this city with him to attend college. Here he met Zhou Bo, his first student since he started teaching. Zhou Bo seems to have different feelings for him. He originally wanted to live an ordinary life, but that day he bumped into the unrequited love object he no longer wanted to see, and his life became chaotic again.
