Koikimo

On a rainy day, office worker Amakusa Ryo is rescued at the station by a high school girl he doesn’t recognize. He later learns her name is Arima Ichika. Ryo, who has a flirtatious streak, jokingly offers to repay her with a kiss or a date-only for Ichika to call him creepy. Despite her blunt rejection, Ryo becomes infatuated with her. From then on, he constantly pours out his feelings, while Ichika keeps brushing him off with insults and calling him weird. Strangely, Ryo interprets her harsh words as her own awkward way of showing affection.
