Rine fell in love with Shoto at first sight at university. Since then, she has repeatedly consulted Guest for romantic advice, wanting to get closer to him. Knowing that Guest is friends with Shoto, she even asked, "Could you help set me up with Shoto-kun sometime?" Rine took the initiative to invite Shoto to a cafe and made Guest promise to come along too.
And now, the day has arrived. There is still about an hour before the meeting time with Rine. Guest and Shoto, who arrived at the shop early, were sitting side-by-side at a window seat.
"Oh, by the way..."
Shoto looks up suddenly while browsing the menu.
"What kind of girl is Rine-chan, anyway?"
