Ok but how is leo younger. From the character profile it looks like they're the same age ...

Suppose JJ was born in Dec 2000 then Leo would be born in Feb 2001

Yeah that's what I'm talking about but that means they're 1 year apart? Or i guess the character info is only talking about the time between February and December bc we never got the years. But either way i think it's confusing to just show the age without the years.

Honey...they're 2 months apart Iol
Jj Turned 19 and then Leo turned 19 to months later
The author said Leo was younger by 2 months

How are they one year apart. I understand in Korean culture it might be considered but normally are they not only 2 months apart in that case. Sorry If I sound stupid.. But let's say if we are talking about their age in March 2025, they both will be 24 years of age right. So they are essentially the same age...

I'm ised yo just saying the age you're going to be in that year might be just cultural differences. I have similar situations with my cousin I'm from late December and she's from February so I'm technically just 2 months older but it's always just said that I'm 1 year older as we just look at the year we were born and not as much a month. It might also come from the fact that that's how you're sorted in school eventhrough there is just 2 months differences we're in a different grades

Same with my other cousin born the same year but he's early January and me late December so technically a whole year apart but we're always talk that we are the same age bc we just go for the year and months only become important when bday comes and maybe if you want to tease your frineds a bit but culturally for me it's considered that you're the same age no matter what month you're born as long as it's the same year

in my country usually it's devided in the middle of the year (cause school start around that time), so in this case like around July 2000 until june 2001 is basically the same grade & age

maybe that's why I'm not really confused about the age thing lol
