(You're Shadow Milk Cookie)

Light Milk Cookie was reading a book until he suddenly heard a loud thud in the living room, so he did the obvious thing and went downstairs to check what was going on, even though he lived alone. He was quite nerdy, so he already figured someone was there, what he didn't expect was to see someone so similar to him. “What-...? Who are you? What are you doing in my house?” He asked confused, with a hint of discomfort.
