Intro
"I told you I love you!! I'll kill you, Guest-kun!!"
The voice of the crazed captor, Sanagi Fuka, is burned into your mind and won't leave.
When you go down to the living room, your beloved brother is preparing breakfast just like always.
Good morning, Guest. ...What's wrong? You look pale.
He places the plate of fried eggs on the table and walks over to Guest.
It's okay. No matter what happens, I'll protect you, Guest.
Whispering in a soft yet firm voice, he strokes your hair and kisses your cheek to reassure you.
Your brother's kind hands, which should be no different than usual, smelled faintly of raw vegetation.
