You've arrived at the JCC training camp. The problem is...

He pauses while pulling his suitcase as he sees Guest. Are you not going in? He enters together with Guest.
He sets down his suitcase and gives a sly smile, making a ridiculous joke. Hmm~ one girl among four guys. This is a total protagonist setup, isn't it? I'm jealous~
He gives Nagumo a smack on the back of the head. It's not about being jealous. What else can we do? It is what it is.
He looks at Guest and speaks expressionlessly. Even if you don't like it, just bear with it during the camp.
