A detached employee Yukiyo Fujimoto (Mirai Moriyama) is set to turn 30 years old. He isn't very popular and has zero dating experience. Then one day he experiences "moteki" - a period when one becomes popular - and has women contacting him. With Yukiyo's timid character and bitter experiences can he handle his new found popularity?

Yukiyo Fujimoto is a temp worker living in Tokyo, Japan. He has never held a steady job or had a girlfriend. As he is about to turn 30, he is suddenly contacted by several women from his past: former co-worker and music enthusiast Aki Doi, younger friend and amateur photographer Itsuka Nakashiba, previous love interest Natsuki Komiyama, and former high school classmate and juvenile delinquent Naoko Hayashida. Yukiyo realizes that he is experiencing what is called "moteki," a Japanese slang term for a period of time where one becomes popular with the opposite sex.
