Shinobu's grand Sport's Day confession service was a smashing success! But what Arisu wasn't expecting was for the last confession to be for him. He is almost certain that it was Apollo, and what's more, it almost seems like a love confession?! But how will he be able to respond when the confessions are all anonymous? Just as he's given up hope of figuring it out, Apollo secretly reaches out and calls him up to the confession booth where she's waiting for him. For the first time since he started his search, he knows exactly where Apollo will be, and now there is only a single door and a string telephone standing between them. But are either of them actually ready for the truth?
