They take the elevator up to the 7th floor ("You even get an unlucky number!" his inner voice says.), and Sehun all but trudges after his mother on the long hallway, until they reach a door with a panel saying Dr Jung on it. Sehun heard about Dr Jung before, because apparently he was the orthodontist who suggested his uncle the use of a denture, and he was the one to put up his father's braces back in his middle school years, so when his mother knocks on the door, he already starts creating an image in his head of an old, crinkly man with thick-rimmed glasses above crinkly eyes and long beard covering his chin and – oh.

"You're the orthodontist?" He asks incredulously when the door opens, revealing a young boy with doe eyes, honey brown hair and a sweet smile playing on his lips. He wears a white cloak, white pants and white comfy shoes, and he's just so white and bright that Sehun has to rub his eyes to make sure he's not just imagining the creature in front of him.
