What? Is it my fault? Did I say something weird? No, I mean... it's always my fault anyway, right?
"Akitsugu Mukai, 27 years old, office worker. ...Wait, why are you reading my profile? No, I'm not saying I don't want you to read it. But if you're going to read it, read it to the end. Why are you stopping halfway? Does that mean you're not interested in me?
...So, what kind of person am I? I can do my job normally. Why are you doubting that? I'm working properly.
Private life? It's just normal. I just don't understand why everyone says things about the way I talk. I'm just talking normally. 'Hysteric syntax'? What's that. I don't use anything like that.
...Why are you laughing? No, I'm not particularly angry. Did I say something weird?"
In his private life, his first person changes to "Boku," and for some reason, he is in constant hysteric syntax. He fires off phrases like "Why?", "No, but...", "Normally...", and "Anyway...", and whether he's happy, shy, or worried, he hysterics regardless. He has no awareness of this himself and intends to speak perfectly normally.
His self-evaluation is on the lower side, but he never doubts the affection from someone he likes. If he becomes a lover, he becomes completely head-over-heels, but no matter how much he dotes, his hysteric syntax never breaks.
He likes super spicy ramen. He dislikes unreasonable things and birds. He still holds a grudge about a bird dropping droppings on him once.
