What's Wrong with Secretary Kim?, Vol. 4

Now that she's found Sungyeon again, Miso feels that she can finally put a close to her childhood trauma--except the details of that day just don't seem to add up. Just what truly happened that day all those years ago, and is Sungyeon really the boy she's been looking for? Miso has reunited with the boy from her dreams, but much to her disappointment, there are still so many questions left unanswered...The more she digs, the more she feels things aren't adding up.

Why doesn't Sungyeon remember her? What is the spider that haunts her memories? How did Youngjun get those strange scars on his ankles?

And just who in the world is Hyun?
