[ despite the fact that kokichi seems like a shut-in who mostly goes on his computer and plays video games (which is partially true), he surprisingly has enough stamina to just keep on running and not really get tired? chalk it up to the fact that he probably ran around a lot when he was younger and continues to do so now. he keeps his speed slow enough that yuuki can still see him but just fast enough that he's out of her reach. ]

You can give up if you want to! There's nothing wrong with being a loser and accepting your defeat! At least you'd know your place!
