It's the same old club room, but the vibe between Io and Ryuu has changed. Have they had a fight? But then again, the others reason, they didn't get along very well back when they first joined the club... Then, when a fight breaks out, the cold war between the two second-years ends up getting the Battle Lovers in big trouble!
Without that, they might have 
never spoken to each other again.
Wenn das nie passiert wäre,
De no ser por eso tal vez
no hubieran empezado a hablarse.
De no ser por eso, tal vez
no hubierais empezado a hablar.
Sans ça, vous seriez peut-être partis
en restant fâchés l’un envers l’autre.
Senza quella, forse non si sarebbero più parlati.
Sem aquilo, talvez eles nunca 
 tivessem se falado de novo.
