No, he didn't give them from Ido (as in Ido didn't give them in the first lifetime). From the early chapters we know that Sejin struggled to make up his mind, that he came to a conclusion that he won't steal the docs and he was given a USB by Ido and he took that to his father which wasn't what the father wanted.
In this timeline (the first one) we are shown that Sejin had not formed any bonds with Ido so he is going to steal the docs.
It's a pretty important difference.
Thats what I was trying to say like sejin struggled in both life times to betray Ido but what I still don't get is why his father' wanted the info if he and Ido are partners
Didnt we already know that he gave the documents info to his father from Ido already like why waste a whole chapter on retelling this
