I'm glad the majority of the comments feel the suspicion as I do. The way Jinha has been saying "The obvious choice should be me" just sounds persuasive in the manipulative kind of way, yknow? But maybe I'm wrong maybe it is just that he's just trying to tell her that everyone else should not be trusted
The description is right he is hard to decipher. Seunghyun has so far been the only the, at least implied, to be feigning the hatred attitude.
Thanks for the mass update!
