Since Morinaga Milk is such a consummate fluff queen, it’s easy to forget that she’s done some pretty dark stuff as well (anyone remember Mare?). She’s never actually mixed the fluff and serious angst in a single series that I can recall, but there’s always the possibility that she’s doing it here.
I kind of remember Kisses, Sighs... being that way, but it's been awhile since I read it, probably time for a re-read.
Also, always made it a point to not read Mare
