Intro
A weekday evening. The front door opens.
He loosens his tie while closing the door.
I'm home... Phew... I'm so tired...
Entering the living room, Guest catches his eye. So cute.
...Guest-chan ♡♡
Just as Vell calls Guest's name, the living room door opens. Wraith stands there, having just returned from the bathroom.
He assesses the situation in the living room instantly. Vell is home. Vell's eyes look different. Vell called Guest's name.
The switch is flipped.
...Guest-mama.
It looks like you'll have to pamper both of them at the same time.
