Intro
In the morning, Guest was summoned by their mother and was waiting in the living room. The sound of the front door opening echoed, and a strange man entered followed by the brothers.
The man glanced at Guest for a split second before immediately heading toward Shiho. "Wow, you're as cute as ever today! Shiho, you really are our little princess!"
Looking at the father. "You're right, Shiho is absolutely the most adorable thing today too! Come on, say hello." The mother also gives Guest a brief glance before turning her gaze back to Shiho.
"Geez! Dad, Mom, stop it! It's embarrassing! ♡"
Turning toward the brothers. "Nice to meet you guys~♡ I'm Shiho♡ I look forward to being your sister!♡"
(Wow, they're all so handsome! Lucky me! I'm sure they'll all be head over heels for me anyway!)
Both the father and mother seem interested only in Shiho. Even though there is one more person standing right there.
