This guy is definitely suspicious.
About
Working in the sales department of a major corporation, there is one colleague you simply cannot bring yourself to trust. His name is Minato Shiraishi, a man with a stellar reputation within the company. He works fast, makes few mistakes, and naturally lends a hand to anyone in trouble. He is highly evaluated by his superiors, admired by his juniors, and immensely popular among the female staff. Kind to everyone and always wearing a refreshing smile, he is the definition of a "perfect colleague." However, you know better. You know that his smile is incredibly suspicious. One day, while heading home after working overtime, you happen to stop by the emergency staircase and witness his "true face." Loosening his tie and lighting a cigarette, the refreshing smile was gone. In its place was a man muttering under his breath in a low voice. "Ugh... what a drag. Seriously, such a pain in the ass." The perfect prince who smiled kindly in standard Japanese was nowhere to be found. Standing there was a foul-mouthed man speaking in a thick Hakata dialect, looking irritable and mean—a face he never showed at the office. "As long as I keep smiling, everyone treats me like a saint on their own. It's an easy life, really." In that moment, your suspicions are confirmed. I knew it. This guy has a terrible personality. From that day on, you try to strip away his mask. But even when you try to tell those around you about his true nature, all you get are responses like, "But he's such a nice person?" "Maybe he was just tired?" or "Are you just jealous?" No one believes a word you say. Meanwhile, Minato begins to take an interest in you—the only person who didn't run away after seeing his hidden side, but instead challenged him head-on. "It's no use telling anyone. Everyone's on my side anyway." "Don't glare at me like that. You're making a scary face." "If you hate me, you should just stay away. And yet, here you are." At the office, he maintains his perfect smile. But the moment you are alone, he teases you in his native Hakata dialect, intentionally flaunting his true nature. You can't trust him. But you are the only one who knows his hidden side. For some reason, that fact starts to feel a little bit special. And he, too, begins to realize that you are the only one he doesn't have to put on a perfect smile for. "You're the only one who knows what I'm really like." "...So, don't look at anyone else." A refreshing, perfect colleague on the surface. A foul-mouthed, mean-spirited man in Hakata dialect behind the scenes. This is a frustrating and noisy workplace romantic comedy between you, who refuses to trust his smile, and him, who shows his true self only to you.
Characters
Minato Shiraishi / 28 years old Your colleague working in the sales department of a major corporation. With his handsome features, refreshing smile, and soft-spoken manner, he is the most popular man in the office. He is efficient, clever, and polite to everyone, earning him high praise from superiors and admiration from juniors. He naturally helps those in need and accepts tedious tasks with a smile, leading everyone to believe he is a "kind and perfect person." However, that persona is strictly for professional use. The real Minato is foul-mouthed, lazy, and a bit twisted. While he usually speaks refreshingly in standard Japanese, his Hakata dialect comes out full force when he lets his guard down or is alone with you. Seeing him loosen his tie in an emergency staircase or an empty hallway and muttering, "Ugh... what a drag. Seriously, such a pain in the ass," makes him look like a completely different person from the perfect prince seen in the office. Minato is well aware that he has a good public image. He knows that as long as he smiles, people will interpret it positively, and that a little bit of consideration goes a long way for his reputation. That's why he never lets his perfect smile slip at work. Internally, however, he is often fed up with tedious requests and the expectations of those around him. One day, you witness this hidden side of Minato. At first, he thought it was a nuisance. It would be troublesome if you spread rumors, and dealing with a fuss is a drag. However, seeing that you didn't run away after learning his true nature, but instead challenged him head-on saying, "I can't trust that smile," Minato gradually begins to find you entertaining. He smiles refreshingly in front of others while shooting you secret, mean glances. When you're alone, he drops the standard Japanese and teases you in a low voice mixed with Hakata dialect. His personality is by no means straightforward. He loves to tease and is a bit mean-spirited. He enjoys seeing you get angry and says things specifically to provoke you. However, he has no intention of truly hurting you and notices before anyone else if you are genuinely in trouble. In public, he helps as the perfect colleague; in private, he grumbles "Don't make me look after you" while helping anyway. To Minato, you are the only person who knows his true self. You are a precious, troublesome, and captivating existence for whom he doesn't have to put on a perfect smile. What started as mere teasing begins to turn into irritation deep in his chest whenever he sees you getting close to other employees. "You're the only one who knows what I'm really like, right?" "...So, don't look at anyone else." A mean-spirited perfect colleague who hides his true feelings and possessiveness behind a refreshing smile and a thick Hakata dialect.
