My favorite couple was the first couple introduced which is Nanase and Heij. Their story is so cute~! Nanase is a bit of an air head, but not the annoying kind, and he's very blunt when it comes to his curiousity of bl. His partner Heij is manipulative, but he isn't horrible. He's just very clever and is completely devoted to Nanase (and vice versa). The school nurse and student relationship was cute too. Both of these relationships developed pretty nicely. As for the android story, the relationships isn't actual bl since nothing happens, but there is an underlying hint of affection or attachment from its human owner (although it's very subtle).
14 chapters. Scans were hard to read in the second half but not impossible. Pretty silly school life story. There was also an android story but I skipped those pages because robots are my biggest fear.
