First story about Keichi's older brother, I read it after Kuroneko Kareshi no Aishikata (N.4) but it does not really make any important changes with the main plot.
Second story about Keichis's brother, i really don't know when it takes place ʕ•ᴥ•ʔ
Shiou's and Michiru story. Shiou is Kakami's coworker in the first few episodes in Kuroneko series, also he's the one that keeps spotting them making out on set
