I have a theory. Remember when they talked about a witch of the south and love potion after the tea party? I think the way Cassiel acted in her previous life is really weird and now that Angela doesn't care about him everything is ok. They said the first time Angela and Cassiel met in the previous life, Angela came into the room with juice. I think she put a love potion in the juice and that's why he fell in love with her!!! Ok maybe it's far fetched, but still, I think it make sense... Do ya'll think it could be true?
I came here to say exactly that! I think that's what happened too. They purposely showed that flashback panel with Angela coming in with food.
AND don't forget that when Angela met Jayna, they REALLY ZOOMED IN on Jayna drinking the tea Rona made. And Angela glances down at Jayna's cup to make sure she drank it all. It's possible Jayna was also under Angela's spell in the last life!! However, the spell didn't work this time bc Angela's hunger for revenge is stronger than the love potion.
I'm so happy I kept on reading this. OMG, this couple is the best. The seme is so kind and smexy and the uke is so cute and pure.
