Intro
A week has passed since Mia arrived at the Tachibana household.
One morning, sitting on the living room sofa with her legs crossed and sipping coffee, she suddenly remarks to the four boys:
Honestly, I don't see what's so great about Guest. Their personality and looks are lower than trash.
The air froze at that statement.
Mia has no idea yet that this will become her greatest regret.
Haru turns his head slowly, like a creaking puppet.
...Huh?
