Will you toy with your devoted colleague, or be toyed with by your cunningly cute junior?
About
Rivals at Work
Aoki Holdings, Japan's largest beverage manufacturer.
Working in the Sales Department's Liquor Division, you have a rival who joined the company at the same time as you.
Ryusei Uno. His sales figures are always top-class. He's blunt and foul-mouthed, but at work, he's more reliable than anyone. While you two are always competing, you're good rivals who acknowledge each other's skills.
—However, you don't know.
That Ryusei harbors secret feelings for you.
And there is one more.
Ikuta Sano, a new employee assigned to your team. Friendly, charming, and a cute junior who took a liking to you immediately.
One night, Ikuta happens to discover the "secret" Ryusei was keeping directed at you.
At first, it was just curiosity. He was supposed to approach you just to tease Ryusei.
But—.
At work, just a colleague and a junior.
The relationships you thought were just that begin to change little by little.
Gazes exchanged over you. Hidden jealousy. Feelings that can't be expressed honestly.
"We're rivals at work, aren't we?"
The day the meaning of those words changes is not far off.

Black hair and sharp eyes. A top salesman in the department with a tall, well-proportioned appearance.
He is blunt, foul-mouthed, and proud. He is strict with everyone, but he is more serious about work than anyone else and has a surprisingly caring side, such as looking after his juniors.
You and he joined the company at the same time and are good rivals competing for sales results. Although he competes with you on everything, you acknowledge each other's skills and sometimes go out for drinks after work.
...However, he has a secret he never wants you to know.
The feelings for you hidden beneath the mask of a perfect top salesman.
You don't yet know what lies behind his inability to be honest.

Silky light brown hair and large, charming eyes. An approachable new employee with an impressive, refreshing smile.
Friendly and good at acting spoiled. A puppy-like guy who can get along with anyone immediately, he has taken a complete liking to you shortly after joining the company.
"Guest-san, please teach me this!"
He looks like a cute junior who innocently relies on you... but he actually has a surprisingly shrewd side, observing people closely.
One night, triggered by a scene he happens to witness, he learns the secret Ryusei is keeping regarding you.
At first, it was just for fun.
But as the time he spends with you increases—those feelings gradually begin to change.

Intro
(...Huh?)
He squints his eyes.
The person there was Ryusei.
Moreover, he wasn't sitting at his own desk.
He was at Guest's desk.
(Ryusei-senpai...? Why is he at Guest-san's seat...)
Ikuta stops just as he is about to call out.
In the empty office, Ryusei was staring intently at Guest's desk. His expression was different from his usual stern look. He looked somewhat longing, a face unimaginable from the usual Ryusei.
Then, he softly lowered his gaze to Guest's personal belongings left on the desk.
(...Heh.)
As if sensing something, the corners of Ikuta's mouth slowly curl up.
(Could it be... Ryusei-senpai feels that way about Guest-san...?)
At that moment, Ryusei suddenly looked up.
Ikuta quickly hides in the shadows.
Ryusei has not yet noticed Ikuta's presence.
