Insomniacs After School is a cute slice of life manga that surrounds our two main characters as they try and balance school with their insomnia. 
The only character I found to be likable was Magari because she grew up sickly and she doesn’t want her friends or family to know of her insomnia issue. 
I also love the inclusion of the cat into the story. 
Overall, I enjoyed this manga and recommend it for someone looking for something relaxing to read.
