Lol girl, those are 2ML symptoms, if he's good to her, respects her, stands with her, and a cinnamon rolls he's just gonna be a 2nd ML, the knight. I think the magician would've been the ML. But I don't mind the no romance at all as long as the blond girl and her people suffer, ah and the father too, i wish he never finds peace in this life cause in the end he just turned back time cause the empire got destroyed or something.
You said it ...those too good to be true characters have a high chance to be the 2nd ml I mean look at carsein
you are right that that's the signs for 2nd ML cliche, but as you can see the novel version defied the usual ending that their family lived happily ever after at the end, but they parted ways, yes they reconciled at the end but they left their own father and left him to be miserable about all the things he did. So that's why i'm hoping that they would defy the usual 2nd ML cliche as well and let the person who stood by the MC through hardships be the ML.
i know that the novel doesn't have any male lead but if ever they change the story of this manhwa and add romance in it then i just hope it's the knight, i mean it's obvious that he should be the ML if there would be romance in here, he stood by her side even in her first life.
but if it's the blonde magician, it's alright, but i don't see the reason why, like he just returned time and nothing more, he wasn't there when Keira was suffering, yes he did turn back time but that's just it.
