きのうの君とみらいの君へ ~思春期の6人の物語~

What makes this a good beginner book in my opinion:

• For a kid's book, pretty normal Kanji usage with Furigana
• Short stories that are all pretty similar in terms of vocabulary
• Many of the core terms easy to guess, so you don't need to specifically learn those (レズビアン -> Lesbian)

I thought it was very easy, the vocab is very repetitive (people mostly talk about gender, either in a sense that they love the same gender or in a sense that they aren’t their assigned gender) and it is mostly in a school setting. The only thing I struggled with was very specific school types (in the first story she goes on to study biochemistry I think?) but honestly I could’ve just ignored those words.

The stories usually go like someone is queer and feeling isolated by not knowing other queer people or their friends/family not accepting them. Or about them coming out and being afraid of the reactions. The non fiction nature of this book makes it fairly guessable even if you only understand parts of the sentence.
