you’re being dumb. While Cassiel abandoned Jayna due to being drugged by a love potion, unlike Ruve, he didn’t sexually, physically, (a bit verbally), emotionally, and even psychologically abuse the MC (killed off her only family member after having her grovel at his feet too

). Jayna being able to be near Cassiel just shows that she wasn’t traumatized like the MC with Ruve.
