i watched the preview of ep 5, it seems like he doesnt know she's the caller yet?there was a scene when he was…
some people who read the webtoon said he knew since the beginning she was impersonating n406 but he was just pretending he didn’t know it. in the k drama it’s kinda different, we’ll see that probably at the first he’ll just find out she can talks and after he’ll know she was impersonating n406
I won’t open the page 😭
