Koikimo

恋と呼ぶには気持ち悪い

High-schooler Ichika Arima catches Ryo Amakusa, a twenty-six-year-old womanizing salaryman, just before he falls down a rainy staircase and hands him her own lunch on the way to school. Ryo turns up at her best friend's house — his younger sister Rio's — and announces he has fallen for her, then begins courting her in earnest with daily flowers and dinner invitations she finds, in her own word, kimochi-warui. Each rejection only seems to deepen his pursuit.
