@nefelibatapoetry21 I already thought and started. At a certain age an tattoo will show up on your forearm that somewhat resembles your soul mate (there will be screen shots of what they look like) Sakura is gonna have a Chinese ancient/ spiritual dragon and suo is gonna have like cherry blossom tattoo (aka a Sakura tree) (I can't find a picture I like, So I might draw his of what I have in my head) also I already have the ships. I was gonna just put a random like oc girl for Kiryu, but then I saw a picture on TikTok and so I'm gonna ship Kiryu with......well you'll find out in the fanfic. hehe. Also if your gives you any physical contact your tattoo will glow, others will see the tattoo, but only the person with the tattoo will see the light glowing color, but onec the ship either kiss or confess to each other the color will be permanent, but not glow. I'm also gonna try to make it like episodes long meaning it takes place as Sakura begins high-school. Every thing will be the same like the anime, but with ships and the AU. so there might be spoilers.
