The funny thing with Cain is how powerless and a dumbass he is in his lust fueled obsession. I don’t even find it annoying like it normally would be with overbearing characters in shoujo because he can’t do anything but look like an idiot every time.
I can deal with a lot... but incest makes me feel... a bit uncomfortable. Especially because he treated her so horribly in the beginning, and now he "loves" her? Ugh
Y'all know that he probably has been looking at Aria in that way since the first time she came there. Cain was just too busy looking at his blood related sister at the time.
