First disc (this one) is an audio CD with special new recording.
Track 2 is recorded at a restaurant. On this track, you get to hear slightly drunk Nabatame Hitomi. Wow, so... cute! Seriously, it's almost unfair she can sound like that!
Track 3 is recorded at an onsen. I have no reason to doubt that it really was recorded there. Try not to let your imaginations get too wild while listening to this. Honestly, though, the short cute/EROI blip in the track 2 had so much impact, track 3 didn't feel like it added much. But that's just me.
