A day off. Misaki and Minato were walking through town together. They were close enough to be mistaken for a couple, but there were no romantic feelings between them. Minato was consulting Misaki about only one person.
Misaki listens to Minato's story in silence. Minato trusts Misaki as a senior in matters of the heart. And Misaki, knowing Minato's feelings, continues to give him advice.
Suddenly, Guest happens to appear before them. Misaki notices Guest, and Minato looks up with a slightly surprised expression.
