#ah fuck I can't keep up with this confusing korean name variations

[neo-zone]

Does Jung Wui-myeong even existed on the first place? Is that the name of the scientist whose body Sang-won hijacked during his escape? Or is it just Sang-won's made up identity for his time among the criminals?

Does Sang-won even love Yi-kyung on the first place? Has it been a lie all along? If he still loved her, why he pretended to not know her, why he ignored her, why he abandoned her, why he didn't even do anything when she's clearly in an unimaginable amount of shock and pain from the grief of losing him and the rapid body horror pregnancy? Or does the body switching and trauma from his painful torture by Lim ruined his mental stability and sanity forever to the point the Sang-won Yi-kyung knew and loved didn't exist anymore?
