Koi to Yobu ni wa Kimochi Warui

One rainy day, salaryman Amakusa Ryou is saved by a high school girl he doesn't know at the station. He later finds out that the girl is Arima Ichika. Ryou is somewhat of a womanizer and to repay her for saving him, he suggests giving her a kiss or going out on a date with her, in which Ichika tells him he's creepy. This, however, opens a new door for Ryou and he falls madly in love with her. Ever since then, Ryou tries to overly express his feelings to Ichika. Ichika just keeps insulting him and says he's being creepy, but he just seems to take it as her way of showing affection towards him...
