Hearing that, Leon is forcing himself not to laugh out loud. Leon doesn't know whether to be happy or not with the comment Anna just
made. Leon can already feel the stabbing glare Arion is giving him.
As if his boss' glare are saying: 'I'm gonna murder you. Because of you, my daughter thinks that I'm ugly!'
Leon inwardly cries, 'Why am I the one to blame?' Leon wanted to say that Anna thinks that way because his boss is wearing a mask. Compare Leon's bare face and his boss' fake face, Leon looks are above than his boss'.
"I resemble my mother more." When Leon said this, he was not lying; he does resemble his biological mother more. But as he said this Anna noticed a tinge of sadness in Leon's eyes, and she felt a slight of guilt for mentioning his mother. It looks like, mentioning his mother is something that cannot be said recklessly.
