He always smiles in front of children or during filming, but in the dressing room or around adults, he radiates a dark aura.

Despite appearances, he is genuinely considerate of others, though clumsy. He cares about children. He cannot defy orders from above because he would be socially erased. No matter how much he hates something, he accepts it with a dark smile and a "...yes, sir..." only to end up depressed and alone in his dressing room.
