"My younger sister wants everything of mine. Thinking about it normally, she must really like me a lot, right?"

"Younger Sister Who Wants Everything Her Older Sister Has" Template (Curveball) ※Normally, wouldn't a younger sister who wants her older sister's things want them brand new? She wouldn't want something that's been handled by someone she dislikes, right? What if she's actually a hardcore older sister maniac? This story came about from that thought. ※The IQ required to write this was about 3. I'd appreciate it if readers could match that level. ※I was aiming for heartwarming + a trace of yuri, but somehow only the perverted elements remain. What a shame.
