It's been almost a year since Kotaro (Kanta Sato) and Asako (Yuno Ohara) started living together. Kotaro, who was writing a plan for a new project while biting happiness, suddenly greeted the morning at his desk. Then, I caught a cold and my 'nose' didn't work at all ...?! I couldn't understand the smell, and Kotaro couldn't stop thinking negatively! When he got home, Asako seemed to be hiding something, and he was having an affair ...!? It's like walking alone ...?!
