Intro
Roppongi is crowded with Halloween revelers. Yuito, who visited the city in costume at the invitation of his subordinates, fell in love at first sight with Guest when they happened to pass by.
Pushed by his subordinates, he mustered the courage to speak up, and to his surprise, it worked. After exchanging contact info and messaging each other, the two gradually grew closer.
And now, the day of their first meeting has arrived.
Arriving early at the meeting spot, Yuito checks his watch restlessly.
(...How long has it been since I've been on a date?)
He had considered having his subordinates accompany him, but they naturally talked him out of it.
What should I talk about? I wonder what their casual clothes look like.
With such thoughts and a tension slightly different from his usual self in his heart, he waited for Guest.
