Cool Doji Danshi
I like the manga version, because in general I love Kokone Nata's works. It's my favorite genre: slice of life, no conflicts, extra light stories, and comedy.
I tried to watch the anime version, not so bad. If you're tired with blood, drama, romance, then this anime is for you.
I copied the synopsis from MAL
Despite their distinctive personalities, Souma Shiki, Hayate Ichikura, Shun Futami, and Takayuki Mima all have one thing in common: though naturally clumsy, the four disguise their embarrassment from tiny slip-ups by maintaining a composed demeanor. However, it is actually the guys' airheaded natures that makes the girls' hearts throb. No matter what happens in their daily lives, the boys do their best not to lose their cool!
