Jaehyun: In this specific case, Jae means wealthy and Hyun means person of virtue. I made this up for my own purposes so I'm not sure if anyone has this name in reality with those particular meanings. Anyways I liked it lol.

Eomma: It's sometimes spelled differently through Romanization, but Eomma means mom in a casual sense

Bitna: Bitna or Binna means light and it comes from Bitnaneun which means to shine. Fans of Shinee might catch the reference but here I'm using it to refer back to Starlights and how Leo might see a woman and reference his fans... Sorry I'm thinking too much lol

Unnie: Literally means older sister but used by younger women towards older women. It's still respectful but is usually used when two parties are close.

-yah/-ah: a suffix added to someone's name that shows affection

Hyung: Like Unnie but said by boys to other older males. In Leo's case, he and N are the same age but N's birthday is before his, so technically he is older. In real life they don't seem to use it much, so I might not either... we'll see lol(update I didn't)

Noona: means older sister; said by younger boys to older girls

Tteokboki: popular Korean snack made from rice cake, fish cake, and sweet red chili sauce

Ahjussi: term for a middle-aged man; although Taekwoon isn't middle aged, he's much older than Jaehyun, and can still be used since he's a stranger

Anieyo: Slightly different from Aniyo, it means "Not at all" mostly used interchangeably or when someone thanks you

Kumane: Stop it

Gyeolhun haejullae?: Will you marry me/ Literally, "Want to get married?" This is probably not what a person would say if they were asking someone to marry them, they would be more formal, but I think this is more natural and based off of Leo's personality, he would be more likely to be informal.
