I'm pretty sure it's a shoujo but it might not be. It's about an older sister (probably in high school) and a younger one in elementary school, the high school one is complaining about how easy elementary schoolers have it, and they swap bodies the next day and she goes to school as her younger sister and it turns out the younger sister is popular but she doesn't have it easy and she puts in a lot of effort. That was basically it.
I can't find it, whatever it was it's not under body swapping tag on mangaupdates. Might have been part of an anthology.
