Absolutely loved this. A lot of books and manga that address asexuality do it on a relatively surface level. These characters are very layered. It starts out sort of very basic, but as it opens up and Chika considers herself and the world and listens to her friends and other people in the world around her there is genuine complexity to how sexuality and gender and romance and relationships are discussed without it feeling too preachy or non-fictional. It still feels like a nonfiction manga while still being very informative. Great bit of lit.
