Mizuto and Yume used to date, but now they've suddenly become stepsiblings. Both of them agree that they don't want to do anything that'd disappoint their newly remarried parents. However, neither of them can accept the other as being the eldest sibling in the relationship. So they both agree to settle the matter with a game. Whoever does something in conflict with what people might consider normal sibling behavior, loses. Making them the younger sibling.
That's better than you using mine.
.ما زال ذلك أفضل في نظري
Ist ja auch nicht so
schlimm im Vergleich.
Me repugna escucharte
decir mi nombre.
Me da repelús escucharte
decir mi nombre.
Je préfère ça que l’inverse.
Preferisco quello che sentire te
chiamarmi col mio nome.
É melhor do que ouvir
você dizer o meu nome.
Лучше так, чем слышать
«Юмэ» от тебя.
