He didn't die right??! can someone explain to me.

Unfortunely, he is probably die by suicide. The key word suppose to be the question in the last panel. If everything is my fault then why do I need to continue living? Then the end. That question is an indication of suice thought so even it is not clear it most likely true he will do it. So sad. He is clearly brainwashed in his whole life like how it is his fault when he is raised like that? Very unlogic, right?
Just a little observation... I could really tell that Hui is starting to have feelings for him but, because of his transformation and since he isn't human after all he doesn't even know what the feelings he's been feeling is it love or just his physical change. I liked how the author made use of these traits. It's sooo cute you can really feel the emotion on Hui's part. CAN'T WAIT FOR MORE UPDATESS.
