I love that there are two yandere(s) in this (They're, are they?). Also, i really like the dynamic between Caelum and Felix - ooh, the rivalry, can't wait to see more of that.
--And Spoiler below--
And, i just want to say i really loved this part (idk if i remember it correctly, but i really love their dynamic in this one):
Felix: "There's a lot of sh**ty people in this world. I'd like for none of them to touch them. Who knows what they'd do to such a kind person like (y/n)."
Caelum: "If you really have no intentions of doing anything... it wouldn't hurt having someone else around too. Only for (y/n)'s safety. Only that."
Argh! I can't wait for more! :)
