This is making me wanna re-read the novel again, why is it so good ㅠㅠ

did sayoung knew that he was J right from the start???

When Sayoung was younger, he only knew J, so he couldn't see, only hear and feel. So Sayoung only knew the distorted voice and how his hand and face felt. So I think he didn't know from the get-go, but eventually something clicked within him c:

i see !! thank you(▰˘◡˘▰)
