I didn't think I would read this here, I love Athanasia and the story with Clude. This was one of the first manhwas I started reading. The closing of the story for me was dramatic. Lucas is Lucas, I didn't know he was animated. I'll have to watch it. I'm going to watch itrrr hahahahahaha.
I think it would have been better if it was Japanese, it feels weird with Chinese language. I replayed the video.
Something fantastic about the story is how Athanasia seeks to avoid death and how Claude loves her more than anything. Even when she escapes or loses her memory. There are slow aspects in the manhwa, but that is not the closure, rather it happens this way to lengthen one of the most popular series at that time. :)
