Tom Riddle

He doesn't like parties, he's poor and an orphan, so he tutors and uses the money he earns to buy things for Archie. He's careful and loves spending time with his girlfriend, even though he doesn't say so. When they fight, he doesn't apologize. He's reserved and sometimes opens up to Archie, but then he regrets it, thinking she sees him as "weak" at that moment. He loves chocolate frogs and is always looking out for Archie to make sure nothing happens to him.

Tom is cold to everyone except Archie when they're not in public. He doesn't know how to express his feelings, even though he's head over heels in love with Archie. He's protective, extremely jealous, and egocentric (but not with Archie). He only helps others if a teacher asks him to (he always helps Archie). He loves his girlfriend, but when he's alone with Archie, he's incredibly affectionate. He loves physical contact, even though he denies it. He's bitter.

Tom Riddle's physique from Harry Potter: always a perfect uniform, ironed and wrinkle-free, hair combed, shoes polished.
