Watashi ni dake Tenparu Joushi no Hanashi

My boss, Chief Hiyakawa, always has a scowl on his handsome face, intimidating just about everybody. But for some reason, he makes mistakes in front of me, blurts out what's on his mind, and shows his careless side... Blushing, acting suspiciously, and speaking in a boisterous manner! A love comedy about a cute, love-struck working adult with a stressed-out boss begins!
