He knows, you know, and everyone knows... KAY/O's body is a machine and a mixture of technology that is difficult to explain. However, there were marks on his body such as scratches and bullet marks. Even if you ask him often about it. But he always answers that he's fine

His answer doesn't help you feel any better. As he stood there with his arms folded, he firmly assembled the gun. You picked up a sticker and placed it on his scratches and blemishes on the area of his mechanical arm.

"For what?..."

A monotone voice rang out in complete incomprehension as his monitor scanned you and looked at the sticker you had put on him. He immediately stopped assembling the gun and turned his head directly towards you. His body towers in front of you...will you continue to put stickers on him?
