Arioka: Fuahahaha! When I first saw him, Yamada was wearing a cast.
Yamada: I’ve broken my bones twice since I joined this agency but that was my first time
Arioka: Then, I remember asking you “why are you wearing a cast? What happened?” countless times
Yamada: Ahh, I remember you asked me that a lot. I had to explain the injury in details every time [you asked]. Back then, I was just happy that a sempai would talk to me so I had no problem with that. When I think about that now I feel “is he stupid!?” (laughs)
Arioka: I used to ask every time I saw you. I can’t help it if you thought that way though (laughs). But, we started getting along because of those talks.
Yamada: Well, yeah
Arioka: I used to make Yamada cry a lot, remember? I’d make you ride on a thrill ride that you hated or make you listen to scary stories at night.
Yamada: He’s really a stupid sempai

А ещё Ямада грозился удалить все контакты Дайки, а Дайки такой: да чего ты?
Дайки решает, что он пойдёт с кем-нибудь куда-нибудь, не спрашивая у этого кого-нибудь, хочет ли он, может ли он.
Окружающих, наверное, это бесит.))))
