He is a paradox of some sort, but he doesn’t even really know himself. Puzzle Rui gets bored easily and usually isn’t amused. he likes puzzles. He thinks of himself as superior and that he should always he in charge. He’s cold, mean, and bossy. The truth is he’s lonely, and the guilt is killing him, even though he’ll never tell anyone and continue bottling it up.
