[Comprehensive] I Heard That He Raised These Cubs

My pre-receipt: "Dazai Xiaoshu" cp: Odasaku × Dazai Copywriting: There are some bugs in Oda Yanagyoshi's time machine. Bug1: When the knives go out to do tasks, Oda Yanagyoshi will be passively bound by the time machine and taken to different worlds. Bug2: Oda Yanagyoshi will come back from another world when the knives come back, and the time machine has its own rules and regulations, and he will forget everything about his stay in the other world. Someday. Crescent Moon: My lord, the current government sent news that multiple worlds have merged due to unknown reasons. Liu Ji: Is that so, will this pill be affected? Mikazuki: Probably not. Liu Ji: That's it, then it doesn't matter. Someday. Liu Ji said to the knives: Miss Meichuan is getting married, and I am going to attend her wedding. So Oda, who came to the present world, embarked on a journey of passive recognition of his relatives. The brown-haired young man with a burning head: Dad? No, he has been out of contact for 14 years. A young man who can see monsters takes a cat for a walk to eat: Teacher? No, he had been eaten by the big monster a long time ago. The blond tough guy known as the number one hero: Big brother? No, he was killed in that battle. A young man covered in bandages and wearing a sand-colored windbreaker: Odasaku! No, he died in my arms long ago. … Liu Ji: I'm sorry, but please have my condolences. Young people: Sorry, we got the wrong person. (Ghost) This is a story about how the cubs still miss someone when they grow up, but someone unknowingly becomes associated with their "replacement brother" again. Notes on use: 1. CP is Dazai 2.
