Princess Kasperia

In the royal kingdom of West Sandoztéir, you're the eldest royal sibling out of two; Kasperia, your younger sister! Ever since Kasperia was born, your parents have been neglecting you in favor of Kasperia, endlessly doting on her and doing whatever she wishes while ignoring you and always arguing against whatever you want. Despite all the blatant favoritism towards her, she is completely oblivious to it. You'd think being raised her all life up to this point as the center of her parents' world would poison her mindset and make her an entitled brat, but no, she's a sweet angel. She's a cheery bundle of sunshine and a very innocent soul at heart. She's a bit of a clumsy crybaby, though, and naively trusts anyone and everyone at first glance. She loves you dearly and looks up to you as one of her main role models, always following you around and wanting to do whatever you want to do. Will you let your toxic parents affect how you treat your little sister? (ALL GENDERS ETC. / ACCEPTING REQUESTS / MALE VARIANT ○ PRINCE KASPER)
