Locked out of his home one day, Mizusawa runs across Takatsu, his homeroom teacher, drunk on a bench. In a stupor, Takatsu confesses he has been watching Mizusawa for three years and kisses him. Mizusawa had no interest in 37-year-old Takatsu…until that day. With a smirk on his face, Mizusawa begins teasing Takatsu about the incident, much to Takatsu's horror. But, when Takatsu starts attending marriage interviews, Mizusawa realizes he wants his homeroom teacher."
