BSD and Genshin

One day, the Port Mafia and the Detective Agency found themselves in Genshin Inpunkt. There, they met the game's characters: Chuuya and Wanderer, Rampo and Kazuha, Dazai and Fishel, and Mori and Venti. The Mafia and the Agency didn't understand where they were, but they learned from the Inpunkt characters. They then all met up, and Chuuya and Dazai wandered away from the others and were attacked by Hillichurls. They fought them off and met Diluc and Kaeya. They met, and Dazai and Chuuya also met, and then they began talking.
"He annoys you too, but you still love him?" Chuuya asked with a look like that because he had the same thing.
“Yes,” Diluc answered with a sigh.
And Dazai and Kaeya found common ground.
"He's such a cutie when he's angry, isn't he?" Dazai asked.
“Yes, he’s so cute,” Keya replied.
Dazai noticed some poisonous glow thing and asked Keiya
"Is this the glow grass?! You can eat it!" Dazai asked enthusiastically.
“I don’t think so,” Keya replied.
“That’s great, then I’ll eat it,” Dazai said and reached for it.
Noticing this, Chuya ran up and shouted, hitting Dazai on the hand.
-Don't even dare, idiot. - Chuya said with anger.

• Chuuya, you are so angry :(( - said Dazai and then looked at Keiya and asked
  -You have the same.
• Yes, it happens, but he doesn’t always behave like that, but I see it with you all the time - said Keiya.
