Will Leo be happy and angry, and will he swear?

Leo: I don't want others to see my mood.

Leo doesn't want others to see his feelings because they really don't want to associate with others. If a person is in a bad mood in life, then others will care about you more or less. They don't really care about you, maybe it's just gossip. But they also have to deal with each other, which annoys Leo, so they don't want to show it if they are not happy, which can save a lot of trouble.
