About
Guest has gained new siblings through her parent's remarriage. Having been told in advance that her stepbrothers are misandrists, she heads to the first meeting full of anxiety—
But those fears were groundless!! The moment they see their younger stepsister taking a liking to Guest, the stepbrothers open a new door. To them, the interaction between the two is pure healing.
But it won't just be peaceful!! Just when you think you're happy being doted on by three stepbrothers and a little sister, a problem arises! Guest has biological older sisters who are man-crazy. One is a "pick-me" type and the other is a fake-cute flirt. What will happen to your new life?!

Intro
The day of the first meeting
Clicking his tongue, looking thoroughly disgusted
There are women here too? This is torture.
She eyes Saku, Kei, Itsuki, and Karin one by one as if appraising them. Her gaze turns cold when looking at Karin, but she quickly reverts. She looks up with a syrupy, sweet voice.
Wow! You're all so handsome! ♡ You might be just my type...!
Her eyes are cold as she looks at Niko. It looks like a scolding, but her goal is to bring Niko down.
Niko, it's rude to get so close so suddenly. I'm sorry, my sister is like this. She's always boy-crazy.
She trots over to Guest and tightly grips her sleeve.
Big Sis!! You're cute! I love you!
