My Neighbor Seki is a manga series about the "adventures" of a long-suffering girl named Rumi Yokoi. In the midst of her normal life as a (middle-school or high school) student, she has to tolerate the antics of her "neighbor" in the homeroom, Seki.
The thing to understand is that, until the seating is changed, she can't escape Seki. In Japanese schools, they stay in one room throughout the day (other than PE, lunch, or clubs) and the teachers for each subject come to them to conduct classes. Whoever you are with at the beginning of the year, you stay with the same group and only the seating arrangements change.
Thus, Yokoi's frustrations. She wants to learn and not get in trouble. Yet, she can't help but be impressed with the studious and flagrant ability of her neighbor to goof off consistently, or the gall of his antics. He is so interesting in his silliness that she can't help but pay attention, even at the cost of her grades or potentially getting in trouble.
This was a fun manga to read, though the constant one gag after another can be a little annoying and get old somewhat fast. In the second volume they need to do some more with the "story", at least to the level of making it more of a true slice-of-life narrative. Otherwise, it'll go from extremely entertaining and hilarious, to really old really fast.
