@Thistleheart1 Hello! Sorry for the late reply, I'm not very often on here anymore. Thank you for mentioning this.
I wrote those books back in 2014, where I was a young 12 year old who didn't know much about anything outside of my schoolbooks. When Nico said he had a crush on Percy in HoH, it was very new to me and I honestly didn't understand it, especially since the word 'gay' had never been explicitly stated (that I recall). I had grown up in a sheltered community with no exposure to anything other than white, heterosexual couples. I know you're probably not looking for excuses, but honestly, I was writing for fun then, and just went with what I saw around me in media. I'm definitely older now and way more exposed to current matters, and after learning more, am a supporter of the LGBT+ community. I didn't mean any harm by it and I didn't know any better (and it was probably a reader's request for me to include that situation in the story). Thank you for reading this :)
