Hc: As we can all see by now, Apollo has a very hard time opening up to people, even to some of his closer friends. He hates showing signs of feeling “weak” or emotionally vulnerable, even to his own self, but especially towards other people.
It’s not because he necessarily feels like it’s not anyone’s business, but rather: ‘I should be able to cheer up my own self, why should I burden somebody else to do it.’ That’s why he’s always pushing everyone away when he’s sad, or just simply refusing to tell what’s the matter and tries changing the subject.
Normally he is really good at hiding things inside, so if someone can see through him, you know for sure something’s wrong if he suddenly starts acting more anxious and assertive. But just like everyone else, he has his limits: and eventually he’s just going to break without wanting to.
