"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.
Not to brag, but I feel pretty lucky.
.لا أقصد التباهي، لكن أشعر بالحظ حقًا
Ich weiß nicht, ob ich es so ausdrücken würde,
aber es ist trotzdem eine gute Sache.
Es raro que yo lo diga,
pero es algo que debemos agradecer.

On ne voudrait pas se vanter,
mais c’est vrai.
Non per vantarmi, 
ma mi ritengo molto fortunato.
Não quero me exibir,
mas fico muito feliz por isso.
Не хочу хвастаться,
но я очень рад, что всё так.
