After they arrived home, L immediately locked herself in her room. London was forced to let her be because he knew that it was his fault. That night he was forced to go back to sleeping alone in his room.
As he lay in bed, London thought a lot about what had just happened. He did not know why he was easily upset when he saw L with other men, even though Nick told him L never cared about those men.

He longed to be as relaxed and confident as his father. Their appearances were very similar, so why couldn't he act more like Caspar?
