Baiyin Yuxing's strength first classroom

The temptation of free tuition and all-inclusive food and accommodation made Baiyin Yuxing resolutely enroll in Yucheng High School.
Following the ordinary genius Arisu Sakayanagi, the wild genius Kouenji, and the artificial genius Ayanokouji, Ikusei High School has added another hard-working genius.
Just before the four geniuses competed on the same stage, a voice from the future appeared in Baiyin's mind.
They claimed to be their future daughters, and their mothers were from four classes in the same grade.
Baiyin: No, how can I compete in the class if you guys do this?
Daughters: Dad, what are you talking about? Don’t you like us? Don’t you want us to be born?
Baiyin: Well, no, it’s because there are so many of you. How can I feed you? Okay, Daddy will work hard for you!
Three years later, I watched the man become the student council president, graduate from Class A, and achieve two small goals in school.
Sakayanagi: This is a hardworking genius. I think this is what I see.
Horikita Suzune: It's really surprising.
Shinomiya Kaguya: No, you are wrong. Only Shirogane who falls in love with someone is the strongest!
Qianhua: Yes, Shirogane is the strongest when he falls in love with one person, and when he falls in love with many people, his strength is multiplied! He becomes even stronger!
Shinomiya Kaguya: ...Fujiwara-san, shut up!
