Ok I'm a bit confused so help me out.
The white haired one, isn't he an angel?
They said he just recently started seeing ghost but how does he knows so much about angels then? When the ghosts trashed the mc's house, the white haired one said "i should have gotten rid of them sooner", why didn't they realise that he's the one killing ghosts????
Did I not understand something while reading or??

He is definitely human. When they first met him, Taker was looking at him and he saw the white sphere inside the guy's chest: that's his soul. Dojin said it later, that angels check the souls of humans to see how powerful they are, and if it would benefit them to take their souls if they died.
He probably always saw ghosts and angels, he just showed up at the university recently. It's not weird that he knows a lot about them if he sees them too, it seems like he doesn't like them so maybe he studied up on them to be prepared and know how to avoid them or stuff.
Anyways, something is definitely fishy about him.. not that he said he wanted to get rid of the ghosts (he doesn t like them after all, and even Taker once asked Soohoo if he should get rid of Pea). But there was that ghost in the uni bathroom, and the ghosts seem to think he has something to do with that white thing that killed their friends.. most importantly, he gets too close to Soohoo..
Well, we don t know much about him. We ll have to wait and see. I hope I helped and sorry for the long reply.

I wonder if the mage is the one that saved her after she was executed.
It hurts a bit when her father makes that hurt face and realizes she changed, but he deserve to suffer just as much as she did

Yeah but by the looks of it the father has been put under a type of spell, that may me why he suddenly only thought of the blonde as the true daughter. He said the "dream" made his heart ache and he's been having horrible headaches lately so....might be the blonde child and someone else's doing.

The mage that "sent her" back is her father invoking the waterspirits power to its fullest. if you wana know more.
Link to a pose i made about spoilers from the novel.

I honestly don't know if he was under a spell, because when the blonde girl interrupted the party he spoke with confidence. His body expressions said that he was ok to do the trail because he knew that the bloodline would react no matter how many years pass. He said it previously when Robert, the old butler, told him about the lasy researching about spirits. Then, once the blonde girl showed her water magic (lets called it that for now) he seemed devastated, I say this because of the way his eyebrows are going upwards, he also feels unresponsive like when a person who trusted his gut but the outcome is another and rejects that outcome. When he slapped her he really was rejecting her. He truly didn't like her ever since she was a child or since her mother was pregnant. As for when he sentence her to death, like I said he wanted to question her further but the nobles were asking for blood. So, he comply with the damn nobles request. Fools!! All of them!!! (╯°Д °)╯╧╧
I would like to see more of his expressions -- specifically when he has those "nightmares" to see if he was under a spell or if he was just allowing for an outsider to come into his home, mentally and emotionally abuse his daughter and neglect his only son. Either way, I'm happy the mage was able to send her to exactly two years and two months before all this happened.
I knew he was in his 40s but damn..he looks good
Yea cuz his body didn’t age for 22 years
