[All] Actual birthday vs. ID birthday

Is your actual birthday the same as your registered birthday?

I'm about a week behind lol

I guess my parents reported my birth late 😂

Now that I think about it, I didn't ask for a specific reason.

Now, if I change it to my original birthday, my resident registration number will change.

There are so many things that need to be changed and I think it will be a hassle

I'm just living like that ㅋㅋㅋㅋㅋ
