The Skeletons in Our Closets

This is an alternate universe where Yamaguchi finds out before high school starts that they're non-binary!!
Their best friend from childhood just confessed to them that he also has feelings for them. He even kissed them. What's going on? Yamaguchi's next adventure awaits, an awkward encounter and a trip down memory lane. To a life they wish to dispose of. But why? And will it affect what is happening with Tsukishima? Will Tsukishima's sudden return after months without contact affect their relationship? How will he make it up to Yamaguchi? And will he be honest about the journey he had after a tragic "accident" dawned on his family?
(Credits to my dear friend Atlas on Discord who came up with the idea and participated in writing the story!!!)
Edit #1: I've been trying to locate who the artist that made the fanart that I used for my cover is to no avail. I can't find anything that confirms who made this and without a watermark it makes it even harder to find. If any of you know who the artist is please make a comment anywhere in the story!!
Edit #2: Hey so this story was made when I was in high but my plans for this story will lead to many mature (aka strong and traumatic) topics so I've changed the target audience and the rating. Sorry if y'all don't like that :/
