People saying that ido should have discussed this with sejin and let him know that he was about to do this, have picked almost nothing about sejin's character yet, i fear.
Sejin has extreme attachment to that abusive family and that disgusting excuse of chairman/father due to events from his childhood. He has severe abandonment issues too. Which is also a result of how his soo called family has treated him over the years and yet he has stayed faithful to them like a dog.
If ido ever discussed this with sejin before doing this, we all know the entire plan would have never ever come to fruition. Even rn, when ido has clearly told that sejin's father promised to literally give their company's only omega in exchange for something as if sejin was some throwaway object, even now when Sejin knows that his father has treated him as anything but a human being, sejin looks like he feels that Ido is wrong here.
So yeah, if sejin knew the plan to bring down that disgusting man down wouldn't have worked out. Ever.
And I'm happy that Ido has come clean about whatever he did. If he had thought about giving sejin time to process and all that, we all know Sejin would have come to know it from somewhere else and would have gotten hurt and then we'd all have said that ido should have mentioned everything from the beginning. So yeah I personally am on Ido's side on this case. Sometimes when people you love can't see that they're being strangled to death by the snake they think is their pet, it becomes important for us to remove it by force. That's all. For a better future, sometimes straightforward approach is the one that works.
Ooooo he knowwwwwsss knowwwssss
