Cute and popular, Nanoka seems to be the type of girl who could get any boy using her so called “tactics”. Accepting confessions and dumping boys at the snap of a finger, she’s never truly been in love… until she met the Cooking Club President, Haru. How can she catch this upperclassman’s attention when she can’t keep herself composed enough to use her so called tactics?

From Osuwari Team:

Beginning of college; checking out the school clubs... Nagi likes the drama club because it has a cool-looking guy whom Nagi thinks is kind. But once she joins the club he makes the club members do embarrassing things in public--and makes Nagi cry. His name is Rin, known as "Sad Yama." He won't let Nagi quit the club--and he won't let go of her either!

Hanamoto Mika is a shy, self-conscious 17-year-old-girl who wants very much to love and be loved. Hopelessly superstitious and unhappy with her current self, Mika tries to find answers and guidance to her life through fortune-telling and romance magazines. She decides to go on a group date with her friends and meets Takada. It’s love at first sight; at least on her end. Soon after, she encounters Takada coincidentally on the subway, but Mika trips and falls at his feet, then runs away in mortification before he could say a word. They meet again on a second group date, but to Mika’s humiliation, he has no recollection of her from the first date! But he does remember her embarrassing moment on the train. He apologizes for not remembering her and then explains that he had lost his contacts and couldn’t see clearly on that first date. Emboldened by his confession, she shocks him and herself by asking him out on a date! This is the story of unlikely relationships, and the trials and tribulations that await Mika and Takada - and their friends- in their search for love.
