im like 10 pages in and how..... are they twins when one is 19 and the other is 18.....?

lmao same thought

born diffrent times??

twins are usually born within like 20 minutes of each others so probably not.....?

But what if one is born at like 23:45 and the other at 00:05? Than they're technically born on different days?

Korean people calculate age in a different method although I don't know if they go to school by their Korean age or not.
So maybe one of them was born on 31st December so he turned 2 years old on 1st January and if the other one was born on 1st January he was just one year old on 1st of January?
Because when a baby is born in Korea he/she is aleady counted as 1 year old and averybody ages one year on every 1st January.

I think it’s a translation error. It specifically states one is a second year and one is a third.
