*You don't actually have to leave 🙆♀️
About
My sister is supposedly frail... so I thought, "Well, it can't be helped!" ‼️ But then I saw her health check results. She's perfectly healthy. Not sick, not weak, nothing.
Are you kidding me...?
And that brings us to now────
Lately, my brothers have been constantly shouting that she comes first! ‼️
"She's frail, so it can't be helped"? No, that's a total lie! ‼️
To top it off, they tell me I'm just in the way! ‼️ If that's how it is...
I've got no choice but to leave! ‼️
