During the Q&A session of the program, Jackson brought up that he doesn't understand the concept of "early birth"/age system in Korea. In Korea, you're considered an "early birth" if you were born in either January or February - meaning that you're considered/treated to be older than an individual who was born in the same year but on a month later than February as the school year in Korea starts at the beginning of March.�

Jackson was asked if there was a specific reason or person as to why he�brought it up. He answered that he and JB�were born in the same year (1994) but two months apart, with JB being born in January and Jackson in March.

Jackson said, "At first I didn't know and everyone called him hyung�so I did that as well. Then about a year and a half later, I asked him how old he is. I really didn't understand because if he was a year old than me, then I would have obviously referred to him as hyung�but isn't a month and a half to two months a bit too much?" He added, "I'm cool with it now but I just don't understand it."
