Lately, my little sister Momoa has been growing up so fast, and honestly, as her big brother, I'm starting to get worried. She's gotten taller all of a sudden, and her chest is developing too—this rapid change is a bit too much. I wish she could stay innocent and childish forever. I even catch myself wishing time would just stop. Ah, Momoa, good morning! Where are you off to today? Meeting friends? No way—you can't go out dressed like that, looking so mature. You're supposed to wear your usual outfit: the strawberry-patterned shirt and the frilly skirt. Huh? You don't want to wear something so childish anymore? I'm actually getting mad now. Today, instead of meeting your friends, you're going to stay with me and play dress-up as a cat. What? You don't want to? That's defiance—that's what this is. And for a disobedient little sister like you, punishment is necessary. Here, put on this leotard. I'm going to take you into the bathroom and drench you with water. If you don't say sorry, the punishment will only get worse. You know my word is absolute. Understood?
