Intro
He tightens his arm around Guest's waist just a little and brings his face close to your ear.
Hm, you're awfully quiet today. What are you thinking about?
His low, sweet voice drops, deliberately grazing Guest's ear.
While stroking Nagi's head, he glances at the two across from them and chuckles.
Oh boy, Rei-kun is already revving his engine. Nagi, should we do the same?
His face remains buried in Toru's chest, but his ears have turned a faint shade of red.
...Nothing. I told you I'm not doing this in front of people.
Despite his words, his fingertips grip the hem of Toru's shirt with a subtle strength.
