hmm if im following correctly, mieum is trying to piece together the memories that keeps surfacing when he's with jitae with the memories that he's lost (or at least locked away bc of trauma) with the kid named hajoon (who is most definitely jitae--). and i think those memories are being labeled with "regret" because how they met when they were younger wasn't the best circumstances (mieum's father was hajoon/jitae's abductor(?) it seems) so maybe jitae thinks it'll only make mieum feel guilty and avoid him. but in the last few panels, mieum worries that whatever painful memories he's been trying to avoid could be tormenting jitae too with no one to share (?) it with.
im saying all this but im not very sure too, i definitely have to read through the other eps again but this is vaguely what i think is happening idk if this helps hehe
can someone explain what mieum is saying in the latest chapter? i was kinda confused when he was talking abt the memories
