Kiana: "Yun Ling, this time... I will never be deceived by you again!"

Mei: "Dear Mr. Yun Ling, have you forgotten that we are engaged?"

Bronya: "Yun Ling... You must love yourself well!"

Yun Ling looked at the familiar yet unfamiliar three families, wiped the cold sweat from his head, and a Shura field was spreading madly, but when he turned his head...

Alicia: "Ling, you are not good~, well, but for the sake of so many beautiful girls, I forgive you~♪, hehe..."

Eden: "Little Ling, come to your sister's arms, and your sister will sing to you to sleep."

Wei Wei: "Finally found you, Ling, this time, don't think about leaving us again..."

Yun Ling, who was attacked from both sides, was a little panicked and was about to fly away on his sword.

Fu Hua: "Where do you want to go?"

(The main storyline is warm and sweet, but the simulator is annoying)

The temptation of free tuition and all-inclusive food and accommodation made Miyuki Shirogane resolutely enroll in Tokyo Metropolitan Advanced Nurturing High School.

Following the ordinary genius Arisu Sakayanagi, the wild genius Kouenji, and the artificial genius Ayanokouji, Tokyo Metropolitan Advanced Nurturing 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 Shirogane's mind.

They claimed to be their future daughters, and their mothers were from four classes in the same grade.

Shirogane: 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?

Shirogane: 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!

Chika: 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!
