Looking For Manga

(kinda long description srry and thx)

Manga about a girl (pink hair and pale skin) that goes back in time. She has an ability because of her mother. She can sing really well and maybe charm people with her voice. Her mother made her drink a potion that made her unable to talk to protect her from the king cause he was obsessed with the mom's voice. The mom ends up dying and in her last life she stayed with the king (who might be her dad, can't remember) and ends up performing for him and the nobles after they discover her voice. She ends up dying in some tragic way and the guy she gets engaged to when she travels back hugs her (?) when she's dying and says something. That's why she goes looking for him after regression. Once she regresses she wears a bunny mask (I think) and doesn't talk because she wants to hide her ability.
