I. . . I came back to update this article, but I still want to write it, and it has almost nothing to do with the main plot. I suggest you wait until you finish writing it before reading it, as you may give up.
Yu is the first in line of succession to the Sato family, as the heir to the aristocratic family. Yu-chan kept her reserved and elegant appearance until she met Zaga Yahiro.
"Classmate Zahe, can you consider falling in love with me?"
He was in a state of infatuation with Dongtang Ming, "I refuse."
"Baxun-san, can I be your candidate for love?"
Zaga Yahiro, who was having an affair with Yamamoto Mei, said, "I refuse."
This is probably due to the fact that Zaga Yahiro was used as Yu Sato's one-sided love throughout his youth, which has been running around and developed into a two-way love.
Ps: If I don't open the trap now, I'm afraid I'll forget about it and force myself to write it down!
