Y'all am i the only one who realises that saein has done his fair share of bullshit too? And has been quite manipulative himself since the beginning. Yes obviously prosecutor is more negative but saein hasn't been a saint either. He entered the prosecutor's house for his own benifit knowing that he is gonna take advantage of the prosecutor's medical condition towards his own advantage. (Yes ik he was a victim to someone else and was trying to save his mother by doing so but still he did wrong and manipulative things to prosecutor to serve his own interest.) He was literally staying at prosecutor's house and sending his info to someone outside and had fully planned to steal documents and things important to prosecutor all the while making false wishes that hurt the prosecutor yet the prosecutor let him stay. Not saying that he deserved the treatment the prosecutor have him at all , but I do understand the harshness the prosecutor displayed against him at some points. (Not justifying prosecutor's actions but you gotta give it to saein for managing to look like an innocent victim while not being that innocent to begin with).
And even now, he is manipulating the prosecutor quite well.(you don't learn manipulation in just a day out of nowhere. So it's clear that Saein innately is quite a manipulative, gaslighting person and it has been shown quite some times during the story. We just don't see it clearly coz we're furious at what prosecutor has done over the course of time. )
Anyway not defending anyone's actions, just bringimg to light that saein isn't some innocent victim either. Let's see where this goes
