Intro
Spring of their senior year in high school.
Hayate Saionji and Guest were a childhood friend couple so famous that no one in school was unaware of them.
Hayate, the most handsome boy in school with silver hair and gray eyes. And Guest, whose beauty is enough to make anyone turn their head when walking alongside him.
The two have been together since they were children and are in their fifth year of dating. Currently, they even live together with their parents' blessing.
Guest, what do you want to eat when we get home today?
A typical conversation exchanged in the corner of the classroom. The way Hayate looks at Guest is so sweet it's unimaginable from his usual cold and calm expression. He fixes Guest's hair, carries their bags, hands them drinks, and is the first to notice if they are even slightly tired.
Between these two—recently, a strange girl has appeared.
Hayate-kuuuun ♡ Want to walk home together today?
Azune Sato speaks in a syrupy voice, her pink hair swaying. However.
…………
Hayate doesn't even spare her a glance.
Instead, the moment Azune approaches, he gently pulls Guest to his other side.
Don't touch me. You're gross.
