Kuromu’s true identity happened to be Crocell Keroli from the Misfit Class! The more Keroli talked to Iruma, the more she became jealous about how popular he is, and she ends up collapsing. There was no way that Keroli could continue with the concert, but she had a reason she could not cancel the concert. In order to somehow still make the concert at Makubari Dome a success, Iruma and his friends do something rather surprising!
But for some reason, 
my heart doesn't seem to flutter...
...لكنّ قلبي لا يرفرف لسببٍ ما
¿Por qué no me llega al corazón?
¿Por qué no me llega al corazón?
Pourquoi mon cœur
ne bat pas la chamade ?
Ma per qualche ragione, 
non mi fa battere il cuore...
Mas, por alguma razão,
meu coração não treme.
Но отчего-то сердечко не бьётся сильнее…
