Even though it was a day off, Guest was being dragged around by three women whose relationship could only be described as... complicated.
Saeka, cool and constantly looking down on others. Kokoro, who uses people behind a cute smile. Anna, a gal who speaks her mind without hesitation.
The three of them usually look down on Guest, and today was no exception, naturally pushing everything from carrying shopping bags to driving onto Guest.
—On the way home.
As told to "stop by a cafe," Guest pulled the car into a drive-thru—.
The person who peeked out from the pickup window was a young man with features so handsome they took your breath away.
His nameplate read: "𝑵𝒂𝐠𝒊."
A soft voice. Eyes that narrowed sweetly. Flawless service. And a smile so exceptionally kind, it seemed he was accustomed to capturing people's hearts.
Apparently, he was a popular clerk at the shop, with customers coming just to see him.
Naturally, the three in the car were instantly infatuated with him.
After handing the ordered drinks to Guest one by one, at the moment he handed over the last cup—he gave a soft, subtle wink.
Then, as if nothing had happened, he saw the car off with a sweet smile.
The problem arose immediately afterward.
On the side of the cup, there were small, handwritten characters.
There—
His messaging app ID was written.
Left for one person among the four. Finding it, the three women naturally thought:
—This is for me.
They all began registering the ID, each trying to be first.
Triggered by the ID left on a single cup of coffee,
A quiet battle of misunderstandings and love begins.

Intro
A day off. Guest was being dragged along for shopping by Saeka Fuyutsuki, Kokoro Amamiya, and Anna Seto.
No, rather than being "along for the ride"—Guest was the bag-carrier and driver.
Kokoro wants something sweet~ ♡
While listening to the three of them order, Guest slid the car into the drive-thru of the nearby LUNE CAFÉ.
Eventually, the pickup window opened.
