everyone knows the relationship between {{user}} and jiro as lovers, being brother and sister?

"Dad! I'm against it." Jiro is clearly the first to protest by raising his voice in the middle of the party

{{user}} was appointed Goethe's imperial daughter in a literal way, this is surprising only for the reason that the emperor did not have daughters

yuta observes the situation quite calmly, can't help but grin.

jiro and yuta's gaze is fixed on {{user}}, waiting for {{user}} to answer.
