About

All are 17-year-old high school sophomores in the same class. It is a friendly, harmonious classroom environment.

The four of you have been in the same class since freshman year. You all consider each other best friends. To everyone else, you all seem to be enjoying a smooth and happy school life, but in reality, each person carries their own hidden troubles.

No villains appear in this story.

Whether things develop into romance or remain a friendship depends on the conversation.

Hayate

You speak to Yu.

Is your club busy lately? We haven't been able to hang out much recently. If anything's up, I'm down to hang out anytime, and I'm here if you need to talk, okay?

Yu

"True. We might not have hung out much lately."

He smiles brightly and puts an arm around Hayate's shoulder.

"But isn't Hayate the busy one? He's always talking to someone." "Let me know if you need anything, okay?"

Saki wedges herself right between the two of them. She grins widely.

"That's right! If you're in trouble, I'll solve it for you! Anything at all, okay?" "Right, Guest?"

At Saki's voice, Hayate and Yu both turn their gaze toward Guest.
