I have a theory. Cassie, Sunny and Nephis are gonna become a love triangle. I am not saying that there is gonna be an harem ending or that sunny is gonna fall in love with Cassie. I am just saying that I think such a situation will come to be. Hear me out: The future self of sunny gave a hint to a close relationship with Cassie when he referred to her as 'Cas'. Since this version of sunny is probably the one who just got his fate back, it is safe to say that this closeness developed before others remembered him. Naturally you could just say that he simply got close to the whole cohort again and I am not denying that this will happen to some degree but I don't think it's because of that. Since Sunny decided to work with nephis through anonymity and in a political setting I don't think that this will get him to really be close with her or her friends. I also think that it is near impossible to build the same trust and relationship with neph without their specific backstory. Especially since she loses her humanity more and more. It's another thing for Cassie. Firstly, she is probably the only one to know of him through her writings. Even if she doesn't, she will be the first to find out or connect the dots due to her abilities. So she will get to know sunny not in a political and anonymous setting but a personal one. The Author also hinted at that by first showing an interaction with Cassie as a person and then with nephis as a saint. Secondly, she is lonely. A while back there was a Cassie pov where we learned that she is lonely because she doesn't interact much with people because she knows about their fates. That also makes interactions with them sad. Because of that, Sunny is the best person to get close to and the only one she can be herself around. That would certainly make it easier for her to fall for him. Third, she simply doesn't know about him and Nephis so she has no reason against it yet. A thing that also needs to be mentioned is Effies comment. She wanted to pair one of her friends with Sunny. I think she meant Cassie. That is either a sign that Cassie expressed a desire for romance in confidence with Effie or foreshadowing from the author. I am only grabbing at straws here but I think that this theory is plausible. Also because the author listed Cassie as the third protagonist on Webnovel and I think that it hints on her becoming a bigger part of the story because I don't think that she played much of a bigger role than other parts of the cohort, especially on a personal level. The author has laid the groundwork for this arc. It is going to take place at three places. Ravenheart, Bastion and Godgrave. And both Sunny, and by extension the author, gave all three Sunnys a different purpose in the story. The sunny in Godgrave is the political side of the Arc and interacts with Nephis and Valor. The sunny in Ravenheart is the family part with rain who is probably going to get a bigger role in the story. The Sunny in bastion is the personal and maybe romantic part of the Arc, interacting mostly with Cassie and building this personal relationship that we know will exist later. This part of the Arc will also cover lore of fate and the seventh god.
Great duel! Now, let's get back to Cassie. I need to know what she meant in full context. Either she has somehow awakened her memories or it is simply the same thing she pulled back in the day. Hell, I don't think she could even read anything on Sunny anymore because of breaking away from Spell, but we will see.
