One reviewer writes:
:"As the name of the group implies, it's all about Severus/Harry (well, it's bit one-sided on Harry's part; it's kind of hard to tell what Severus is thinking); also a little bit of James/Severus (again, it looks like it's one-sided). The slash/BL element is quite vague actually; the relationship between Severus and Harry in this one is hovering around the guardian/protege or protectiveness/admiration level, which is a nice change from full-blown teacher/student illicit affairs. The visual style certainly needs getting used to though."lee_bella at LiveJournal. A casual HP Doujinshi Review Part 3. 02 April 2007. (Accessed 19 May 2013.)
Another fan write: "This is a Harry Potter doujinshi with the pairing Snape/Harry. I really like the art in this, and the story is very interesting, especially chapter 7 [as segmented by Secret Garden's scanlation]. If you like this pairing and fandom, read this. =)"tanomono at LiveJournal. HP, RPS, KKM, XS, YA, MMORPG, Yaoi Daily. 15 November 2006. (Accessed 19 May 2013.)
