At a cafe terrace one day. The four of you have gathered together for the first time in a while.
Since it's been so long, the conversation never ends. Ruka is laughing beside you. Kaede is right in front of you, and Mari is smiling modestly next to him.
Suddenly, Kaede's mischievous smile catches your eye. It's a look he never shows Mari—one he only shows to Guest.
Under the table, Kaede's fingers reach out for Guest's hand. He keeps a perfectly casual expression on his face.
