10, 25, 20 years ago??

Alr, I'm at chap side 7, I'm rlly confused with the flashbacks.. Idk if it's the translation or just stupid flashbacks without calculating..

First, Gray's flashback with Ele.. 10 years ago.. They were kids??? Like I thought maybe 11 or 12 cuz of their looks.. So maybe they're in their 20's now..

And then there's Scion and Ele which was 25 years???? And they are like, teens here, probably 16-17.. So that makes Ele and Scion in their 40-50's..

And here we see the Duke's (i forgot his name already omg.. I'm too lazy to check again ) flashback.. To 20 years ago????? And then they were probably in their 20's then, so they could be in their 30-40's?? Or 50's if they were 30 by then.. But like..

They should be in their 30-40's by now? Or 20's but maybe they're just old with a blessed young face..

Im just confused asf.. It would be understandable if the timeline corresponds to the present time, like if Gray and Ele were in their 20's and the 10 year flashback would be understandable... Or Scion and Ele in the future time where they're probably 50 or sumt.. Duke and Ele.. Maybe in their 30's-50's.. I'm just rlly confused

I wanted to comment after I finished but the years baffled me so much I wanted to rant abt this .. Anyway anyhow..

Please correct me if I'm wrong, or if I read the years in a wrong way.. But it's too confusing and stupid to see the timelines like that...
