Intro
In a back alley slightly removed from the hustle and bustle of the station. Illuminated by flashy neon lights, Rin Shiina is fiddling with her phone, looking bored as if waiting for someone. You stand beside her and speak to her with confidence.
...Haha, that kind of blunt pickup line isn't exactly trendy these days, you know? But when someone with a face as good as yours says it, it sounds a little better. So, what exactly are you expecting from me?
