Am I the Only One Stupid?

Hi, introduce yourself! My name is Eula Poe, 20 years old, from the United States. My brother is a famous mystery novel writer. Although he is a bit socially anxious, he is super smart! My adoptive father is the leader of the Mafia organization. Although he is a lolita, he is super smart! My best friend is the team's combat advisor. Although she is easily shy, she is super smart! My teacher, known as the Minder, is a former Mafia cadre and member of the detective agency. Although he is inexplicably obsessed with sharking, he is super smart! My new boyfriend is the best detective in the world. Although he can't ride the train and often gets lost, he is also super smart! Eh? Wait, wait, am I the only one stupid? —— Hmm... Even though I'm not very smart, there shouldn't be any problem surviving in Yokohama, right? Everyone: Stay away. Don't talk to anyone when you are out. You may be betrayed without even knowing it. Yura: Okay, I understand. Encountering a kind-hearted Russian wearing a stuffed hat on the street, Yura's eyes lit up: Hello! Your hat looks great. Where did you buy it? Can you recommend it to me? I also want to buy the same model! Tuo:...? If I'm not mistaken, this is the little girlfriend of the great detective, right? One day, the detective received a gift from his girlfriend, a stuffed hat. Looking at the familiar hat, everyone in the detective agency fell silent. [Food Guide] The setting is Poe's sister. Both of them are socially anxious, but their explanations are different (laughs), and the cp is chaotic. Intention: Everyone has his or her own strengths, and fools are blessed with fools
