The thing about first timeline Kloff's love is that it got dark and twisted because the bonding was not a proper nurtured one. It was filled with his own insecurities, jelousy, predujices, posessiveness, disappointment, obsession, hate, lust and his desire of revenge. All those feelings affected Aeroc's and caused his misery because he reacted to the bonding too.
Bonding or scenting, in this universe, can be dangerous and something to be afraid of if it fails to connect both individuals.
In the second timeline, Kloff's and the housekeeper talks about a tale about a pair of lovers whose bonding went wrong or something like that but Kloff was surprised because he thought that was just a myth. Like finding your one true mate but it helped him recall and understand why his emotions were unstable and got him excited, for bad or good, at the sight of Aeroc.
It's safe to say first timeline Kloff became mad cause of that but at the same time he was the source and victim of his own emotional turmoil. The bonding only amplified his frustrations and twisted personality. He became an agressor that used the murder of his spouse and un-born child to finally have a excuse to hold on to Aeroc, saying he wanted him to suffer, without recognizing his feellings and face the predujices of being both alphas... he hated him and loved him but he's a very complicated character.
If you were Aeroc and I am Kloff, would you believe me if I said 'I love you' on your death bed, or would you take that as a lie as you asked me to?
I wish the answer would be as direct and simple as one wanted but it's very complicated. In my opinion, when Aeroc asked that, it was a way to test Kloff and see if he finally 'forgave him'. If he actually said he loved him, even without being true or him believing it, for Aeroc it would mean he was forgiven because Kloff actually indulging him would mean a very huge deal.
But Kloff was incapable of doing that, he was not emotionally or physically ready for that. How could he when all that time he was only inflicting pain and taking his revenge on him. Again, Kloff's a very complicated character but he had feelings for Aeroc. Feelings that traveled across timeline in the form of bonding because that it's for life. The third timeline will explain more of that.
Raphiel will get his happy ending in second and third timelines. He even has his own novel with Linus. He must stay away from those twisted lovers tho
I refuse to believe he loved Aeroc in their first life. It traumatized me that no one will convince me that what de felt and did is because of love. Fuck, I cried in each episode. No shit consoled me, my mucus and tears mixed hahahahah I CANNOT. I FUCKN CANNOT.
Some might argue about what happened with Raphel and his child, but I won't budge. Fuck everything, just not Aeroc and his children. Even Raphel's presence in this season was brushed off after a failed engagement and he's gone.
What I saw tho in Bedyki (seme) is his familial love to his children, but that's all. That's all is there to him. Fuck his lust.
