Solution [3]

"By the way, I'd like to invite you as the third member of the said group," I said as I extended my hand toward Akumi, offering a handshake. 

"Wait, the third member? Not the second? I mean, I understand that the first is you but who's the second?" Akumi asked. It seemed like he wasn't bothered to join but rather by the fact that he wasn't the second member. 

"That is confidential. You'll know when the time comes for it," I replied. 

The second member, of course, was Req. I had talked to her beforehand about creating a group and she urged that I count her as a member. Well, I was going to do that anyway since among all the people I know she was currently the most valuable of them all. 

And since I didn't want to tell Akumi about her I decided to keep it confidential. 

"I can't say I like that…" Akumi said, his expression resembling that of a kid who had been denied candies.
