“It’s only dinner, right? I’ll help by pretending to be Hayato’s fiancée.” Hayato asks the couple to help cover up a lie he told his mother, and the wife eagerly agrees because it sounds like something from a drama. Her husband expects her home within a few hours, but Hayato’s mother has also booked a hotel, making it difficult to leave. They exchange several messages until all contact from his wife abruptly stops after midnight.
