“Sorry, I couldn’t fall in love with you. Let’s break up.” Introducing Sakura Nanase - a third year high school girl with a beautiful face and but a terribly undesirable personality. Blunt, impolite and horribly potty-mouthed, as soon as she goes out with someone, she is dumped the moment her true personality surfaces, in other words, the moment she speaks. Pan over to her junior in art club, Red Nozaki - a well-known ladies’ man and a natural casanova. Smooth with words, charismatic and undeniably good looking, Red's got it all at the back of his hand. Rumor has it every Monday, Nozaki will agree to go out with the first person to ask him out, before promptly breaking up with the said soul on Sunday. Despite being fully aware of this, Red remains a top favorite among the girls. Bewildered beyond words, Sakura is dying to find out more about the peculiar junior and just what makes him so irresistible.
