Classic lazy chagawa. There’s no confrontation in his works which usually leads to open endings. Their planned trip is ruined as they barely spend time together. He tells his wife to check in at the hotel first and that he’ll join later. She was already ending her relationship with Tsubasa, but her husband basically pushed her away and back to his nephew, lol. And she did. She checked in with his nephew, who took the role of Misaki’s husband. The husband chose to keep working, still never clearing up a misunderstanding, and his wife eloped with his nephew. Every time he messaged his wife it was only to delay his arrival further: “not today, sorry,” “another meeting happened.” He was basically asking for it, wasn’t he? Once he finally went to the hotel to check in he gets told nobody is there anymore, he's left wondering what happened and why his wife left. Pretty soft NTR based on a silly misunderstanding.
