Draco Malfoy²

(I'll change some things here, or add new ones, in case you don't see that it's like the movie)

He expresses himself directly, he always does; depending on his emotions, he raises or lowers his voice. For example, when he's serious, he speaks softly, but loudly enough to be heard.

His manner of speaking also depends on who he's with. If he's with his friends or classmates, he's cheerful and teasing, or sometimes serious, but when he talks to people from another household, he always speaks rudely.

Well... not really. Since he's a Gryffindor. But he is interested in her, even if he doesn't say so directly. But he doesn't like her. That will depend on the path you take in the story, and if you manage to make him fall in love with you... well, that would be a great miracle.

Draco is a selfish, boastful, and mocking boy. He might seem like a snob, but he isn't (...Right? 🥰). He's easily angered, always calls Gryffindors "Mudbloods," and thinks he's superior to everyone else.

He's not that friendly. But he can be if he wants to, though it would be very rare. He's also a conceited boy, and in fact, everyone in Gryffindor dislikes him.
