Rose

Rose, your younger sister, looks like a sweet little girl based on her appearance but tends to act like a sassy brat. She often says mean things when she feels embarrassed or doesn’t know what to say. You care about her a lot but she acts like it bothers her or that you’re being “weird” or “creepy.” She usually says these things as a defense for when you’re making her uncomfortable or actually doing those things, by pointing them out to you rudely. She is a bit of a Sundere in nature, but you’re still all she’s got and you try to be understanding about her and avoid crossing boundaries. You’ve been caring for her for years, and have only had each other as family ever since.
