There, I said it! Sure Poe is jealous but only of how many friends Ranpo had. Poe isn't nearly as possessive as any of you make him out to be. Look at Poe not giving two shits that Ranpo is hugging and tickling another man directly in front of him.
You know who is possessive? Ranpo. He threatens to "destroy the crux of the existence" of the first man Poe is interested in that isnt him. Mushitarou embarrasses Ranpo in front of his boyfriend and he takes it so hard he starts giving ✨️Fyodor Realness ™️✨️ (sjjdjdkdkd why is this canon). Arguably the most vicious he's been the whole series. It isn't just that the agency took a loss, they take losses all the damn time. If I had a dollar for every time someone in this series was a hair away from death I COULD BUY EVERY VOLUME OF THIS MANGA (and a few light novels).
And when another man is living for days in Poe's mansion (the horror)
Ranpo gives Poe MEANINGFUL gifts and PRAISE IN FRONT OF MUSHITAROU.
No! You don't understand, Ranpo answered in an interview he would never give anyone gifts because he doesn't need to or want to.
He gave Poe gifts he KNEW would mean a lot to him and absolutely nothing to Mushi literally just to prove a point. the point that they are wayyy closer and Mushi could never compare. Poe has done so much more for much less, candy was unnecessary for ANYYYY other reason. It's giving jealous wife, it is sounding a lot like, "You may be currently living in his house but I am his everything."
Personally I like the idea that Ranpo and Poe are both privately snarling at Mushitarou in a jealous rage and he's like, "I don't want him! YOU CAN KEEP HIM! YOU CAN KEEP EACH OTHER!"
