She is technically 4 if they are using that +1 every January 1 age count.. so even if she was born at like say november, she still counts as 1 yrs old and by January, she is 2 yrs old..
I can’t lie I’m still confused wouldn’t she still be to young
So if he was gone 4 years, mom was preggers before he disappeared, (she could have been at least in her first month) and she got the full 9 months, so seol is in the correct age.
What I read was 3 years, tho. He was caught in a gate and entered another dimension 3 yrs ago. He stayed in those dimensions for 300 years (but apparently only three years passed), before returning to Earth, so Soeli being 4 yrs old is reasonable.
If he was gone for 4 years how is that his daughter? She seems way too young to be his kid, she should have been older.
