酎ハイれもんLOVE30S 雨にぬれても

Bug-eyed Katsumi (known as Chuhai to his friends) is a muscle-bound detective determined to use his strength and pig-headed stupidity to rescue his teenage girlfriend from a succession of embarrassing situations.

Based on a manga by Sho Fumimura and heavily seeded with background music from the 1960s U.S. hit parade.
