So, in Chapter Four I realized that it was kind of a confusing chapter in a way, so let me explain. Since Yongguk and Daehyun are now disguised as COMPLETELY different people to hide their identities from the girls and others, I had to make different names for them.
Jaemin is Daehyun
Jaejoong is Yongguk
In the chapters, you're going to see that Jaemin and Jaejoong are in bold and I did that to kind of help you decipher that they're not two new characters and that they are still Daehyun and Yongguk. I hope this helped you in case you were wondering!
