Kyupiko! - Fujimatsu Tenshi no Mismanagement

Fushimatsu Fushio is an unpopular young man whose life is turned upside down by Kyupiko, a lazy Cupid who curses him to be hated by all women. The curse leaves him facing a situation he never chose. Years later, God recognizes how badly Kyupiko has mishandled her task and expels her from heaven. She must now set things right for Fushio.
