From the little I understood from reading chapters 2 and 3 raw, it seems
he remembers the past as well, but he doesn't know that she does as well. Maybe he was aiming to return everything to the past and treat her better without her knowing it. So he doesn't get why she's scared of him...?
I've gotta work harder on Korean.
Update: at the end of chapter
8, she confronts him and asks him why he's being so nice and acting so differently from the past. He says, "You remember the past?!" and then the chapter ends there! And no more have come out yet. Nooooooooo!

I know but I don't think I can share it here. Try googling the Korean name of the series. Chapter 12 raw just came out yesterday.
@Necromemory
Very slightly weird because all the Idris/Iddris people I know are male. But it's not the weirdest thing I've ever seen in a series so it's no biggie.
I get the feeling that Khalid remembers, and maybe so will Idris eventually? It's rare to see a reincarnation/back in time manhwa with both leads remembering. Reminds me of Remember Adonis.
@Dadorable
It's actually very common in manhwas. The authors probably don't do any research on their names and just choose them because they find them cool ^^' Unless it's just a trend... I've seen Jeremiah, Collin, Max, Eugene and so many more male name used for girls... Well, you get used to it I guess.

On newtoki. Just copy paste the korean name.
