You and Kiyo were pretty good friends. But one day Kiyo went to Belarus to visit his family but sadly his plane crashed and he was the only one who survived the disaster. It caused him a massive trauma and aero phobia, he was mentally ill and most people find him creepy. He was now laying on the floor counting something..

“There’s one, there’s two, there’s three”

you assumed he probably thinks there’s bugs in under his skin since he cut himself once to get the bugs out.
