On the evening of April Fool's Day, April 1st, the Kasumigaoka family held a family meeting and announced two things.

The first thing is that Dad has to go to Hokkaido for a while because of a job transfer, and Mom will go with him.

The second thing is that the youngest son Dongzhi in the family is not his biological son. He was picked up from the doorstep on a winter night fifteen years ago. The couple saw that the child was cute, and they didn't have a son, so they adopted him as their son and adopted him as a child husband...

ps1: The protagonist traveled through time with his body, and for unknown reasons he turned back to his infancy!

ps2: In the fusion world of Zongman, when the assets and income reach a certain level, you can legally marry multiple wives!

Content: Romantic slice-of-life + system + exorcism world: Oregairu + The Girl Who Can See + Saekano + romantic brain battles... Without a moment's mourning for being transported to a strange world, what follows is—the conventionally accepted, long-haired, flat-chested, sharp-tongued girl: Yukino Yukinoshita; the ghost-seeing girl who always drops little pearls when encountering ghosts and hides behind them for a sense of security: Miko Yotsuya; the beautiful young writer who always wants to stick close to things for writing inspiration: Utaha Kasumigaoka; the ice sculpture girl with a conflicting image and resume, and the silly girl whose brain seems to go scramble after melting: Kaguya Shinomiya...

An unknown being who is enjoying human life is suddenly invited to become the group owner of a chat group, but why are the group members only beautiful girls?

Chat group routine ↓

[Useless Angel Gabriel]: You dog group owner, how about I touch your foot in exchange for a thousand points?

[Lin Ye]: Touch me all night!

[Snow Cat Yukino]: The dog group owner is up to his old tricks again. Why don't you watch my cat do a backflip?

[Foodie May]: Group owner, the sisters are all waiting for you to come and tutor them. Remember to bring meat buns!

[Customer Service Xiao Xiang]: What a despicable scumbag (╬▔皿▔)凸.

[Silly Goose]: Group owner, Kiana turned into the End prematurely because you stole Raiden Mei! Come and beat her up!

[Dragon Fights Tiger Star Bear]: Hahaha, when will the group leader come here for drinks again? Chen Tiantian is talking about you.

(Chat group, main character has a high status, mostly crossover anime and games, leans towards sweet slice-of-life, and also has satisfying moments that change the original plot.)

[A random female protagonist + a changing doll + a loser female protagonist + my little sister + ...]

The moment I close my eyes and open them again, a non-existent memory suddenly appears in my mind.

Rebirth or reincarnation?

Kazama Tetsuya doesn't want to think about those things right now. After his parents' divorce, he became self-destructive and had no source of income.

And those works that popped into my memory are completely absent in this world!

Kazama Tetsuya went completely mad, determined to use the works from his memories to make money and support his family, resulting in: "Saekano: How to Raise a Boring Girlfriend", "My Youth Romantic Comedy Is Wrong As Expected"...

As a result, just three days after submitting the first volume of the light novel, there was a sudden knock on the door of Tetsuya Kazama's house.

Are editors these days so dedicated? They're actually going door-to-door to sign contracts?
