After stalking one another, high school teacher Takatsu and former student Mizusawa finally start dating. Mizusawa, once a cheeky high schooler, is now a good-looking younger boyfriend to Takasu. A middle-aged man, Takasu isn’t accustomed to dating someone like Mizusawa and having his unrequited love requited. This volume is a collection of stories focusing on Takasu and Mizusawa as they date and build a life together over the years.

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. This volume also contains "You Wicked Spark," a mature love story between a deliveryman and novelist. (Source: Manga Planet)
