Rei and Kaoru have been secretly dating since the end of their third year at Yumenosaki. Rei has grown comfortable with the fact he loves Kaoru and wants to open about their relationship to others.

"Kaoru-kun, dear.. Why are you so worried about sharing our love with the world?"

Rei asks, placing a hand on Kaoru's shoulder.

"It's a lovely thing that we should be open about."
