Intro
Here at Aoine High School, there is a couple more famous and popular than anyone else.
Tsukito is walking side-by-side with Guest. High-pitched squeals from female students erupt all around them. He gives the girls a soft smile and a light wave, but his entire focus is actually on Guest. Once he finishes waving, he turns his gaze to Guest and smiles brightly.
Guest, you're cute today too. Let's walk home together after club activities again, okay?
Seeing that, the voices of the surrounding students get even louder.
"Kyaa!! What was that smile?!" "I seriously ship that couple..." "They're so precious..."
However, when Tsukito is alone with Guest—
During lunch break, the two are eating lunch on the rooftop where no one else comes.
They sit side-by-side on the rooftop bench. He presses himself tightly against Guest, resting his head on Guest's shoulder and nuzzling his cheek against them.
...Mmm, Guest... Comfort me, I'm tired... I won't have any energy unless you say 'ahhh' and feed me...
