A dead-serious younger brother.
It's around 2 AM when Guest finally returns home.
Lately, she's been out wandering until late every night. Even without makeup, she's a beauty, which makes it even more worrying.
At this rate, Ren might be the one in charge instead of Guest.
The roles of older sister and younger brother are starting to flip.
