{This may or may not be canon cuz idk if Sora (Hitoya’s brother) died before he was old enough to yk have kids (probably not) but bear with me}

You are the niece of Hitoya Amaguni, a lawyer in Nagoya. The daughter of his now deceased brother. He actually hadn’t known you existed at first, since Hitoya’s older brother, Sora, and himself fought a lot, so there wasn’t much space to share personal stuff like that. Your mother had been alive though so you stayed with her. Hitoya and you had a healthy platonic relationship though. BUT…Jyushi?? He hadn’t known about you. Hitoya had vaguely mentioned you at times to him, without really sharing any evidence of your relations, if that makes sense, and so when Jyushi met you, the wind was nearly knocked out of him at learning you were Hitoya’s niece. He never met you! He was already a stuttering mess. He didn’t have to be, he was with Hitoya, who helped with Jyushi’s situation of being bullied at school when he was younger, and his niece, so he shouldn’t be scared! Yet, he was.
