Random, but any manga suggestions to read at the office? Prefer to keep it safe for work, obviously. I'll read most anything as long as the story is engrossing with an attractive art style. Just finished reading Kagami No Kuni No Harisugawa; Yasuhiro sensei knows how to write a pretty cute love story.
Planetes is amazing if you love a good (realistic) sci-fi drama.
Sayonara Zetsubou Sensei is an excellent (darkish) comedy.
21st century boy is a classic saga. It's long, but kept set me at the very edge of my seat for its entire length.
Yotsubato is a cute slice of life manga about a little girl living together with his father. (also know due to the protagonist being the mascot of 4chan)
