"Now that I figured it all out, I'm not scared of anything!"

Gaku and Ruka from ROCK DOWN are scheduled to costar in a new stage production of the Botan chapter of the Tsukihana Kagura series. The two meet their childhood friends Eita and Yuta for a housewarming party at Yuta's new apartment and the four get carried away with stories of the old days. Eita and Yuta remember how an invitation from Ruka led to Gaku's debut as a performer. Ruka realizes that Gaku is his 'rival' in a sense, but Gaku doesn't seem to care. Ruka starts to feel frustrated at Gaku's apparent indifference.
It's unusual for Ruka-san 
to turn you down like that.
.من غير العادة أن يرفض روكا-سان عرضك هكذا
Es kommt nicht häufig vor,
dass Ruka deine Einladung ablehnt,

Es muy raro que Ruka
haya rechazado tu invitación así.
Es muy raro que Ruka
haya rechazado tu invitación así.
C’est rare de voir Ruka
refuser une invitation de ta part.
È davvero strano che Ruka ti dica di no così.
É incomum o Ruka-san te rejeitar assim.
Рука почти никогда
вот так не отказывается.
