so much interaction

I think because he remembers a little kid much younger than him. And he was super small. Since Chaejun is super big now and they’re only a year apart he doesn’t correlate that they’re the same person

They were children… do you think you could recognize your elementary classmates now?

Not only that, but shortly after this one of them had a traumatic event happen, like….

It's my point
Friends, yes. Someone i'Ve interacted so much with, i'd recognize name and face of course! But not people i've barely spoken to ! I mean, it happens to me all the time and Im almost 40! so funny meeting people I knew in the first grades of school!

i think we're forgetting here that chaejun had a traumatic head injury and i wouldnt be surpised if seunghyeon did as well (along the lines of concussion) or what he went through was traumatic enough that his memories are blurry/buried

Its a trauma response.. . The human brain blocks out or fails to process memories to protect against stress, no matter how important they are

Trauma is not necessarly the cause. It's not like they spent a year together, we are here talking about weeks, more probably days. It's normal that they forgot, time does It's thing and besides people change as they grow up. Even I have trouble recognising people I used to hang out with for years, some of them I only know because of pictures that we took otherwise I have no recollection of them. And for them adding the trauma to that did not help.

..... I dont remember the faces of kids I saw everyday in my classroom soooooo

Omg? Mind you i dont remember most of my childhood and the person in it.... and i also so forgetfull about name and face of People im interact, even if i meet them daily, after 2 year my memories Will already fuzzy... so not everyone is the same!
