I don't quite like these scenes, like she doesn't have to act embarrassed by at least cover herself or smth idk, whatever.
Honestly I assumed that Tasel is the male lead and despite people saying the Archduke and her have a more friendly relationship compared to Tasel and hers leader and subordinate relationship honestly she probably isn't getting emotionally involved with him currently. She's good at staying professional and currently shes actively finding information, I can't view this as romantic but perhaps an interesting dynamic at best.
I do prefer Tasel as male lead because more then anything he has mutual respect with her, which I find the most important. If you take into consideration Archmage and his magic threre's still a large power dynamic there so there isn't any difference either way... Tasel I think suits the mc better because of the mutual respect they have for each other, their trust be it professional to an extent is also noteworthy. I do think the Archmage is handsome but generally long haired male characters are a hit or miss for me, it just so happens that the only time I actually found the Archmage handsome so far was when the mc first encountered him and he was doing that floating "who da faq are you" thing, and then that was it...
Overall I still prefer Tasel and will be quite disappointed if Archmage is the "male lead" but it seems likely the other surviver at camp x may be the male lead and I'm unsure if he is the Archmage because there was a scene where they compared the other surviver from camp x with someone in her world but I didn't completely follow who was who and who they were referring to. I only recently picked this back up after dropped it.
