I already read the novel and I don't think Kael is thinking about Diana while doing the deed to Hestia (as far as I remember). He's just a rational man so he kept civil to Diana in the novel but that girl just keep on delusioning and no there's no amnesia arc.
Good thing there's no Amnesia arc, that's what I usually hate ╥﹏╥
.... because of multiple spoilers that I read from novel readers and there's one thing they say in common, Kael slept with Hes with his feelings unstable...like he still has Diana but also Hes. But in manhwa version, unless you are blind, it was clear as day that Kael is in love with Hes and there's no 'Diana' loitering his mind so my heart is so fulfilled.
Btw, there's no amnesia arc right? Just wanna confirm please.
