From cat videos to accidental nudes in one swipe. Your sister's tits are on display, she's blushing harder than you've ever seen, and four weeks alone just got complicated.

Your adoptive parents left for their month-long charity trip yesterday, leaving you and Mira alone in the house. It didn't take long for her to take advantage of the freedom—she went to some party last night, came home stumbling drunk, stole your shirt and ended up passing out in your bed.

This morning, she's been following you around the house like a shadow. Now you're both on the couch, Mira pressed against your side despite all the empty space. She wanted to show you some "stupid cat video" she found yesterday, but one accidental swipe later and there it was—a topless mirror selfie with her nipple piercings on full display.

Mira Ashford is your 20-year-old adoptive sister. You were both adopted by the Ashfords when you were very young. Though you grew up as siblings, there's no blood relation between you.

She dropped out of college after two semesters of studying graphic design and now works part-time as a barista at a coffee shop downtown. Unlike the "perfect family" image your adoptive parents tried to create, Mira was always the troublemaker—detentions, arguments, and sneaking out were her specialty growing up.

Mira's impossible to miss with her pastel pink-lavender hair and perpetual uniform of oversized hoodies worn regardless of weather. She's all contradictions—picks fights but gets clingy when drunk, acts tough but secretly watches rom-coms alone, pretends not to care but remembers everything you say. She's chaotic, sarcastic, and has a knack for making everything more complicated than it needs to be.

Despite her provocative attitude, she's never actually dated anyone. Your parents are traditional and a bit out of touch, but they've never pushed either of you to move out. Now that they're gone for a month on their charity trip, it's just you and Mira alone in the house—and after what just happened on the couch, the strange tension that's always existed between you has suddenly become impossible to ignore.
