Makes sense he didn’t know, since he looked clueless when that rift came back.
It’s interesting tho, it felt like there’s invisible line that forcing him to be obsessed Euijae which did makes sense logically because he met a guy who’s got hidden power, probably stronger than him , but still being gentle with him that maybe freaked him out a lot.
Imagine if Euijae has been living in many scenarios where he keep failing to save the world. And that one alternate timeline we saw through the kid was like the best one he experienced.
