Sakura tells Haru.

Hal meets Ricca at the Moon Bride School. Her classmates are clones with the same face as Ricca, and while they have identification names, they are called Sakura. With blonde hair, fair skin, brown eyes, rosy cheeks, and matching ponytails, they seem to distinguish each other by scent as they busily select their future paths. Hal was raised in a good family of naturalists on the surface. In her childhood, she was given two girl-type dolls for emotional education, and perhaps because of this, she has no interest in men. Her parents entrusted their hopes to the Moon Bride School and, in hopes of correcting her, enrolled Hal so she could engage in "proper romance." While everyone calls Hal "Prince," only Ricca calls her "Transfer Student." Attracted to Ricca, who does not choose a prince on the surface as her future path, Hal decides to confess her feelings. Then Ricca says she wants to prove their "pure love"...
