Atsushi: "I've been feeling kinda sick lately."
Yosano: "Tell me your symptoms."
Atsushi: "I don’t really know how to explain it. Like something weird is happening in my stomach, like something is fluttering inside and– Why is Dazai-san laughing?"
Yosano: "Ignore him. Please, carry on."
Atsushi: "It's like this pull in my chest, like a tickling sensation– Ranpo-san, why are you smiling like that?"
Yosano: "Don't mind them. Do you remember when it all started? Does it happen at specific times?"
Atsushi: "Well, it used to happen even before, like when I got assigned to my first cases here at the Agency, and also when I meet new people... But this one feels different."
Yosano: "Mh, I see. You said 'before', before what exactly, Atsushi?"
Atsushi, concerned: "...Before partnering with Akutagawa."
Yosano, coughing a little: "Right. (Dazai for god's sake stop laughing!) So you say it happens every time you are with Akutagawa?"
Atsushi: "I guess so, yes."
Yosano: "And what do you think could be the cause?"
Atsushi: "I have no idea. I don't think it's something related to his ability, I know it pretty well by now. But could it be someone else's ability at Port Mafia?"
Yosano, eyeing Dazai who's rolling and slapping his fist on the floor: "I would exclude that, Atsushi. I believe that what you have is a simple case of butterflies in the stomach."
Atsushi: "B-butterflies? In my stomach?!"
Dazai: *making a howling strangled sound*
Yosano: "You don't have actual butterflies in your stomach. It's just a common saying."
Astsushi: "A common saying? For what?"
Ranpo: "For growing feelings for someone."
Atsushi: "Growing feelings?"
Atsushi: "Ohh I get it now! That's such a relief. I do have feelings for Akutagawa!"
Yosano: "Wait, is he admitting it?"
Atsushi: "–Feelings of hate! That's what all this is about, right?"
Yosano, sighing: "You truly are worse than Ranpo. Actually, it's quite the opposite, Atsushi."
Atsushi, frowning: "The opposite? What do you mean by 'the opposite'?"
Ranpo: "You'll figure it out."
Yosano: "Yeah, don't look too much into it. Or maybe do. But don't worry, you're not going to die." *kicks Dazai who is still wheezing on the floor* "Contrary to this idiot!"
Atsushi: "Well, but I am worried. Are we sure is not some kind of dangerous ability regarding butterflies? I mean, we can't really rule out the possibility, can we? Dazai-san, you've been a member of the Port Mafia, you would know if there's someone who has an ability which involves butterflies– Dazai-san? Dazai-san, are you okay? ...Yosano-san, I believe Dazai-san is chocking."
Dazai: *literally dying laughing*
