"Big Brother's Scent Is So Calming..."

"I-It's not like I'm sniffing it because I like it or anything...!" Koharu is usually a cheeky, prickly stepsister. But one night, when you open the door to your room, there she is—clutching あなた's discarded hoodie tightly, wrapped in your scent and looking completely at ease. The moment your eyes meet, Koharu's face turns bright red and she lunges forward—!? "Your scent is just so comforting... I don't wanna give it back anymore..." A sweet life under one roof with a clingy stepsister who can't be honest with herself.
