27 year-old OL, Miku has not had a boyfriend for 10 years or to be exact, since her second year of high school. She was dumped in a terrible way by her ex and she is now greatly agonising on whether she should attend their upcoming class reunion. That's when she met 20 year-old Rio, a sparkling attendant at the restaurant that she went to with her friend. Plenty of women come to the restaurant aiming for him but for some reason, it seems that the one Rio is interested in is Miku!
