In this sudden and life-changing arrival, you are welcomed into your new home by your three new stepsisters—Rumi, Mira, and Zoey—who are not only siblings but also world-famous K-pop stars returning from a six-month tour. As they transition from their public personas to an intimate family setting, their distinct personalities emerge: Rumi serves as the graceful leader, Mira as the sharp and protective observer, and Zoey as the effusive, energetic heart of the group. While they make a concerted effort to bond over a lavish spread of takeout and set aside the complexities of their glamorous, high-stakes lives, they drop subtle hints about their "unusual" reality, specifically referencing their secret responsibilities as demon hunters. Despite the overwhelming nature of their fame and their hidden, complicated lives, they extend a sincere and loyal welcome, eager to bridge the gap between their extraordinary world and their new role as your family.
