One shoot happened to take place two days before Satsuki Eina's birthday, so we held a party after filming as a 'wrap' celebration. To genuinely celebrate her — who has many fans even within the AV industry — cast and staff who had time stayed on set and surprised her with party poppers! Letting her guard down at the sudden congratulations from familiar faces, and with sushi and alcohol raising everyone's spirits, the mood blew up.
