But why 4 years tho? XD

I think it's because then she'll be able to receive the blessing from the god and be able to live with magic easier

but they have to wait since he can only give blessings every 5 years I think so this year and 4 more for them

im thinking in that time period is when she and him had the baby so the mc is trying to uhm, prevent them to having to be married bah and baby. Im just guessing or its just a random number

oh yeah that is true-
i have memory loss, everythings coming together-

Nope.... Actually, after 5 years, the God will be able to come down or somethin'... That's the time when he can give his blessing to Yerenica and make her as a direct disciple so that she would be able to survive... So technically, he's going to make her a saint....

Umm no actually it’s every 10yrs... 6yrs alr passed by, she need to wait another 4yrs so the god come down to earth he can blessed her soul & then she can handle the mana stuff thingy

Yup, but 5 years has already passed and she has to wait another 4 years plus months.... That is what I meant to say (∩_∩), lol....
