Havi was in love with both since the beginning. Lol

haha lol same, i don't even get why the mangaka decided to go down that route..?? not like she had too
i mean i've read the story years ago, but it was never really established that the demon and vald were 2 different people. i mean yes, of course, in a sense lol, but again..not really. it was more like demonic powers (aka the curse) made demonic vald at night, and prince vald at day haha. as a reader, i never sat there seeing the demon as someone else than vald? and no one really did?? it was more or less a part of vald? so now making it a conscious (!) being IN LOVE with havi, and asking havi to choose, is just ridiculous lol (i mean vald could have just accepted the curse as part of him and the demonic side as part of him if the mangaka wanted to keep the demon so badly)
also, how can havi even choose the demon? like..he fucked vald's sexy body, but the demon was basically a beast w/o any personality aside from instincts like an animal lol...that's some pretty low standards to fall in love with
but as many already pointed out, that story has gone downhill for quite some time now and i truly wonder why the mangaka just never fucking writes a normal end for stories, instead of dragging them on like that haha

they weren't though (referred to that in another comment down here), vald was different people in his own world (i mean..there was also a child vald i think? so it's not like physically they were all one in HIS heart lol) but havi said they were ALL vald at the end of the day, and that even the demon-form was just another side of vald, (born from the curse but still), and that they are ONE existence. his demon form was more or less the more instinct driven, horny honest version haha
so..making them 2 completely different people is actually contradicting what was said in the heart-world because as stated, it was more or less 'the demon-form is a result of the curse but it IS still vald' vs. now 'the demon is a completely different being IN vald's body, with his own mind and history and all that shit.' and even in the heart-scene, havi preferred normal vald over basically boiled down to instincts vald.
But can you really love both Halvi? In all honesty only ONE is really Vald. The other is literally a demon in Vald's body. Don't get me wrong I love this shit to death and though I can't deny the plot crashed and burned along the way, this shit is cracking me up!!! With a bit of heart break cuz are we really gonna end this with Vald keeping the demon in his body so Halvi can fuck him whenever he feels like it? Cuz to me that sounds selfish AF!!! ( ̄∇ ̄")
