Real teaching, starting from scratch, knowing the plot, I just lay down!

Nakano Yuu travels to a world where strength is everything and becomes a highly nurtured freshman.
Good news: It’s an animation I’ve seen, and the character is a rich second-generation, and he has an ex-girlfriend named Arisu Sakayanagi.
Bad news: He has five step-sisters at home, but his father raised him in poverty and required him to make a name for himself in high school!
Being assigned to Class D? And it’s already the end of the first month, and the class evaluation score is 0!
There are a lot of guys in the class who are lagging behind.
So why bother trying? Just lie down!
Anyway, you know the plot, just save up 2000 million and run away!
just.
Arisu Sakayanagi: Oh, it turns out he is also in this school. Then campus life is worth looking forward to.
Ichinose Honami: Nakano-san seems to have forgotten about me, but I will try my best!
Kushida Kikyo: You said I would be fingerprinted by a guy named Nakano Yuu? And I would be expelled from school by him? Impossible, this is absolutely impossible!
Amasawa Kazuka: It's true, Kushida-senpai, just accept your fate!
Horikita: It's so unfair. As soon as the school started, a classmate named Nakano Yuu cheated me of all my points.
Long Yuan: The above retracted, let me say. Nakano Yu, give me back 30 million! 30 million!
