The encounter with Chiba was unexpected. But thinking about it, Lu Shu had gone home with Chiba before, which meant her house was near the dojo.
No, I can't enter her house, Lu Shu thought. Both he and Yaeko were wanted by the Collection of Gods and he certainly did not want to get Chiba into trouble too.
Before Chiba opened the door, Lu Shu had run away with Yaeko. In fact, he had considered killing her, but could not bring himself to do it. Despite knowing her unfriendly intentions when she approached him, Lu Shu saw sincerity in her eyes in the past few days.
Human expressions were never as complicated as comprehension passages… But in the end Lu Shu chose to follow his gut feeling.
Besides, what he had exposed was nothing serious. First off, Lu Shu would recover his own identity after the completion of this mission. So it was not a big deal to let Yaeko know that he was Lu Shu.
