Surely, Minami Maki came up with a quite unique title. It really caught my attention. Just a random fact about S.A: ZA Hana to Yume is a sister magazine to Hana to Yume. The ZA is just the Japanese transcription of “THE” (since the “th” sound doesn’t exist in Japanese and one of closest sounds that can be used to substitute it is “z”).
ZA Hana to Yume has a less frequent publishing schedule – issues appear something like four times a year, I think. S.A was first serialized in ZA Hana to Yume (before moving to the regular Hana to Yume), which is why the first four chapters kept reintroducing Hikari, Kei, and everyone else and why the art between chapter 1 and 2 looks rather different. This is all thanks to Kaeyko from S.A LJ page.
