@OSIDJ yea something like that. Author did narrate how sei interact with other people in previous chapters and he wasn't shown as creepy as this chapter or even hint. that's why I think author failed to express it IF he wants to make him bad guy
did the author draw a new character or what? because we've seen sei interact with other characters that was just fine and he never showed those symptoms that this author suddenly implanted in him. idk whats the plot in here anymore but if the author decided to draw MC as bad guy then he did...
