Asian QL fans:

This does not mean they don't have chemistry. They absolutely do and they are a fan favorite for good reason. I don't think their relationship would ever surpass a complicated situationship. When it comes down to it, there's too much distance between them. It's obvious that they both care about each other. They do well to make sure they would never die and know each other well enough to be soukoku regardless of how often they have seen each other.

But when there's no near death experiences happening, their dynamic is not intimate enough. Chuuya had the unique position of being a teenager who could treat Dazai like the annoying teenager he is. I don't doubt that Chuuya has a deep understanding of Dazai that rivals most people. However, he was also a teenager going through things and wouldn't have the perspective of life that would let him see Dazai the way Oda did.

Dazai would never let Chuuya get so close, but he definitely values Chuuya. He enjoys his company, finds his humanity fascinating, and gets a kick out of annoying him. Chuuya doesn't care to let Dazai get too close either, but also holds his opinion in high regard, calls him while drunk, can scream his name even while in corruption, and even humors their embarassing inside jokes. They don't have to be close or completely understand each other to value each other, but they will never be intimate enough on a casual basis to be relationship worthy.

Because it's literally these 3 guys who have disguised themselves from this 1 guy to go hang out with him. 2 of them know who each other is and also immediately recognised who the third guy is but don't have any proof to back it up. And the third guy also knows exactly who they are but he doesn't care and doesn't even wanna interact with them because he got beef with them.

Yotsuya’s always had that peaceful kind of vibe, and on top of that, he’s always been popular with girls.
