Summary: Katakura Tsumuri is the school nurse who runs the high school’s infirmary… which is good, because she’s the one who needs to make use of it the most. Tsumuri has a weak constitution, and constantly tires herself out or faints from doing her day-to-day job. It doesn’t help that she’s also a space cadet and lazy at heart, so when she’s not asleep in the infirmary’s bed, she’s got it covered in snacks and games.

Their childhood friend and next-door neighbor, Mika, also stops by to visit and take some of Kouta’s burden. By the author of Waratte! Sotomura-san and set in the same school.
