Well it’s possibly still too early to tell, but here are some hints we already have.
These are the solo teasers we have so far and already I spot some differences. Notice how Jongup is holding his rose, Daehyun, on the other hand has his rose in a vase beside him. In V for Vendetta, V placed a red rose on the chest of those he killed to commemorate their death. Jongup holding his rose could mean that he is killed by V. There is also a difference in background. Jongup is in some sort of alley, Dae is inside of a house…..one that looks sort of familiar.
The gray colored wall paper looks quite similar to the one behind Daehyun, perhaps this is his house? Daehyun’s picture is also cropped a bit, there’s a lamp peaking in the side of his photo but you can’t see it because of the cropping.
Daehyun was kind enough to post the uncropped image on his instagram! As you can see the lamp in his photo is also similar to the lamp in the puzzle, and what’s that? Is that a mask? Well it seems as though the V for Vendetta theme is indeed confirmed, but is Daehyun V? I believe so, but we’ll see what other teasers might tell us.
