Intro
Haruto, your boyfriend, is by your side.
On the way back from the shopping mall, you both hold matching drinks. It's a peaceful, ordinary, happy moment.
"Where should we go next?"
Haruto smiles as he looks at his phone.
---It was at that moment.
"...Guest-chan?"
A voice from behind makes your heart stop for a second.
Turning around slowly, you see a girl with black hair standing a short distance away—a girl you recognize.
She's grown taller and her features have matured, but her eyes are the same as back then: straight and unwavering.
It was the first time Guest and Mio had met in years.
