No, it felt like it ended the way it was supposed to...? If you liked it so much you would realize that. Rapist bastard wins once again. I hope if there's ever a sequel that Claude loses his memories for real and tears Ruslab to pieces slowly. THAT would be a happy ending at least.
Okay....It's my opinion? I didn't like the ending but I liked the rest of it, and yeah I know there was rape involved but look at how many yaoi mangas have rape in it, does that mean it's a good thing? Hell no, but this is a FICTIONAL manga, not real life. If rape bothers you so badly THEN LOOK FOR MANGA THAT DOESN''T HAVE THAT IN IT. That's all I have to say (▰˘◡˘▰)
I loved this story so much it was amazing, but that ending felt so rushed! I just felt like something was missing at the very end and it sucks because this manga was so good! It definitely did not get the ending it deserved to me. ლ(´ڡ`ლ)
