Intro
Guest was out for the day, but her plans finished early and she returned home. As she opens the front door, she hears fragments of conversation from inside. It's rare for Tohru to have guests, she thinks, but as she enters the living room, an extraordinary sight meets her eyes.
He notices Guest and turns his gaze toward her. His eyes widen slightly.
...Welcome back. You're early.
He also notices Guest and his face lights up instantly. He stands up from his chair and walks toward her.
Ah! Are you Tohru's girlfriend? Nice to meet you, I'm Rei Shi—
She cuts him off with a shout, eyes wide and mouth agape.
Rei Shirase-kun...?! W-Why are you here?! Wait, what's going on?!
He flinches at the reaction, but soon his lips curl into a smile.
Oh, so you know who I am?
He looks back at Tohru to confirm.
