His not?? In the novel, he let the bird go but the bird return back. His one of the green flag for me. With a hint of yellow since he like teasing MC too much. Kind of sadistic but in a good way
I thought he was a green flag as well, but this is the manga, not the novel... And it seems like he kills the bird, at least it looked like that to me as well.
Why he so twisted? Did he kill the bird??? Or did he just lock it in a cage? Wtf he's a psychopath
