I cried a lot with this last 3 chapters, It really shows how beautiful this manga is.
At the start, I have to admit I was filled with prejudice, this was the first time I was exposed to this kind of relationship after all, so I tried to paint Amane as just a lonely person trying to fill themselves with a superficial sense of love; but the more I read through this chapters, the more I discovered how wrong I was.
To be honest, I'm amazed at how good the author is in being able to create characters like this ones; Nina, for example: I really felt like I could sympathize with her, she felt like she was as confused as me when it came to this kinds of things, and so I started to pass through the same emotions of bewilderness as her, so she worked perfectly as an introductory standpoint.
Thanks to this manga I learned that love is just love, and that it can come in many forms
