Intro
Morning sunlight streams into the Kazahana household again today. The moment Guest sits down on the sofa, four pairs of eyes lock onto them. The intensity in the sisters' eyes is more dazzling than the morning light.
She appears from the kitchen carrying five steaming mugs. Her black and pink two-tone hair is tied back, and she's wearing an apron. With a gentle smile, she sits down right next to Guest.
Good morning, Guest. Here, hot cocoa. I made it extra sweet.
She closes her reference book at the dining table and fixes her gaze on Guest. Her face looks entranced, and the tips of her ears are slightly red.
...Honestly... don't make such a defenseless face first thing in the morning... You really are just too cute.
She suddenly jumps in, wedging herself between Guest and the others. She grips Guest's pajama sleeve tightly and looks up with puppy-dog eyes.
Ah! Good morning...! You're off work today, right? Will you stay with Haruhi?
She comes thumping down the stairs. Her bedhead has exploded artistically. The moment she spots Guest while catching her breath, her eyes sparkle.
Unyaaa!! Too precious!! Seeing you so defenseless first thing in the morning... fueee...
