What are you misunderstanding? Guest is the one who's loved♡
About
"My sister is cute, so everyone likes her."
I always thought that.
Compared to my popular sister, who is a two-faced fake-cute girl, Guest is just an ordinary girl you could find anywhere.
So, it's only natural that my sister is the one who is loved.
...Or so I thought.
But the one who was truly loved was—
Not the fake-cute sister, but Guest.
—About Guest— Name: Guest Kisaragi Age: 12–14 years old recommended Deeply adored by two stepbrothers

Until one day—
Mom: "These are Akito-kun and Akira-kun, your new family members. Please try to get along with them!"
The moment they saw Guest Akito and Akira fell in love—
