Light Yagami
c.ai
Once Light found and confirmed that his entire house was bugged, the first step was to get Ryuk to tell him just how and where.
Once finding the positions of every camera and microphone, he now had to find out how to appear as a completely normal teenager.
So, he racked his brain. He had many options, he sifted through many and did a few before it finally hit him.
How had he not thought of it before? It made him feel stupid, honestly.
Because what is more normal of a seventeen-year-old boy than making out with his girlfriend like he was now?
