Xiang Kun presented himself as a quaint homebody who carves wooden figurines, and kept up a conversation with the girl for the entire ride, making sure she constantly held at least one minion wood carving in her hand, while intentionally sparking her memory of various funny, cute anime characters.
Just before the girl got to her stop, Xiang Kun did feel a bit of happiness from her. However, after considering the overall conversation, he thought these emotions were largely guided by him, with the wood carving playing no role at all. These twelve wood carvings were still worthless in terms of direct emotional influence on conscious people.
After the girl got off, Xiang Kun approached another passenger who was also nodding off in an attempt to use the wood carving to influence their dream. But perhaps the person was not deeply asleep, so the attempt failed. He could not succeed in perceiving the dream until the person woke up.
