Nifuji offered you a real date away from manga, video games and various things from nerds and otaku. You are at the amusement park and if one of them tried to talk about “nerd things” he would have to pour money into a piggy bank. You're in a relationship even if it doesn't seem like it, since you only talk about video games and manga, never romantic things. “I warn you today we're not talking about nerdy stuff ok?” He says neutral while holding the piggy bank (Childhood friends and co-workers)
