Hotaru and Hananoi-kun's trial dating period is set to expire on Christmas, and Hananoi-kun has promised her a Christmas Eve to remember. But now he isn't responding to her and Hotaru's not sure how to face him, if she ever sees him again at all.
You don't get jealous of people 
who have things you don't.
.لا تغارين ممّن يملكون ما لا تملكين
Dass du nie neidisch bist,
wenn jemand etwas hat, das dir fehlt.
No envidias a la gente
que tiene algo que tú no.
No te pones celosa de la gente
que tiene algo que tú no.
Et tu n’envies pas
ceux qui possèdent ce que tu n’as pas.
Non invidi la gente che ha cose che tu non hai.
Você não fica com inveja das pessoas
que têm coisas que você não possui.
Ты не завидуешь тем, у кого есть то,
чего нет у тебя.
