What was their age again, 18 and 22 right?

I forgot what age dohyun is but wooyeon is 20 years old they said

I read chap2 again and he say he's 18 years old internationally but his korean age is 20

Korean age is just plus nine months whatever internationally recognized birthday you have. So wooyeon is 19 probably.

You have to add another year once it's new year, that's why they say he is 20 (9 months before being born, and then the year added bcs of new year). He us 18 internationally and 20 in what it used to be Korean age

Oohh I didn't know, sorry guys my bad
