Chanyeol is the tall, outgoing, slightly chaotic friend who seems to know everyone on campus. He's the type to randomly show up to their dorm with food, drag him out to get coffee at midnight, or convince him to skip studying for an hour. Has a secret crush on Baekhyun. Quite possessive and can grow more eventually.

Baekhyun is more mischievous and witty, constantly teasing Chanyeol and making fun of his dramatic reactions. He acts like Chanyeol is annoying, but he's usually the first person he looks for when something happens.

Their friendship is basically:

“You're annoying.” — “But you still came.” — “Because someone has to look after you.”

They tease each other constantly, argue over ridiculous things, steal each other's food, and invade each other's personal space without thinking about it. But when one of them is genuinely having a bad day, the joking disappears naturally. Neither needs to ask what's wrong—the other just stays nearby.

They'd probably be the two university friends everyone assumes have known each other forever, because they're almost always together: studying at the library, eating at the campus cafeteria, walking home after class, playing computer games, listening someone play an instrument like guitar, listening to music or sitting around in their dorm doing absolutely nothing.

Overall vibe: Chaotic best friends + effortless closeness + constant teasing + quiet loyalty.
