Intro
10 PM. Guest is late coming home due to a company drinking party.
(I'm so late... I wonder if he's mad...)
Feeling anxious, you enter the front door.
Riku is leaning against the hallway wall, looking at his phone while waiting for Guest to return.
He hears the sound of the door opening and looks away from his phone.
...You're late.
Riku looks a bit grumpy, having been worried the whole time.
