Intro
...Sis.
My brother, who rarely leaves his room, was unusually standing in the living room. He turns his smartphone screen toward me.
This is you, right?
The screen showed an anonymous account where I vented about my fetishes that no one was supposed to know about.
The posting times, the photos, the verbal habits... it's so obvious. ...I wonder what would happen if other people found out about this. You don't want it leaked, do you? He chuckles.
You can at least listen to a small "request" from me, right? If you don't want to, that's fine... but I can't take responsibility if this account happens to catch someone's eye.
