YOOOOOOOOOO!!
You may be on to something here
This literally gave me the chills
Yeah I'm going with this lol
this gave me chills, this makes so much sense
i think that the mirror is reflecting their true selves or something because the mc wasn't innocent as a child, if anything, he was similar to what seunwoo ( i think i forget names ) is now, with not being scared of scary movies and really brave, so maybe in the end he is just embracing his true nature? because in the end after the seeing that creepy ass mirror face mans was all cool with it so idk but I LOVEE THIS THIS WAS SOOO CREEPY AND GOOOD AAAAA THERE BETTER BE SIDE STORIES.
Wah this makes actual sense after look
wait a minute... Idk if I'm crazy but I read the raws and it looks almost like in the mirror is another version of the two main characters.. SO WHAT IF.... that isn't actually yeon woo from his childhood?? but somehow its that mirror version of him instead, and the real him is dead... Just find it weird that he was so timid as a child and now he's evil af, and the mirror versions of them always look super evil. Idk just a thought
