Plot
At a shootout, Sara refused to continue shooting, until she drank her champagne as that was the moment when it was at it's best taste. She spoke with Issei Toomine on the phone, who was annoyed by Shizuku Kanzaki. They agreed to go to dinner when she returns and she also told him she had commercials to film for Taiyo Beer, which made Issei a bit annoyed as he knew Shizuku was working there.

At Taiyo Beer, she filmed the commercial and met Shizuku and quickly realized who he was, because of his name. Later that evening. The filming crew went to drink together with Sara. The director chose a wine, saying it was one of his favorites and tried teaching Sara how to hold her glass, but as she tasted it, Sara commented she felt like she was aborting and that the wine was bad. Sara turned to Shizuku so that he can confirm it, but Shizuku stood up and took a decanter and poured the wine and then shaked it. He then presented it to Sara and the director and both of them ended up liking it, commenting it now felt completely different. Sara was amazed at Shizuku's skills, especially how he shaked the decanter without even creating a single bubble in the wine and wanted Shizuku to tell her where he learned it and to teach her too. But then his coworkers interrupted them and Shizuku wasn't able to say anything.
