PORTRAIT OF M & N (M to N no Shozo), by Tachibana Higuichi. First published in 2000 and first published in North America in 2010.
PLOT:
Mitsuru is a stunning beauty from an accomplished family who is seemingly perfect and demure...at least, until she gets hurt. A lifetime of parental abuse has given her a masochistic streak, and the slightest injury leaves her in a daze begging for more. Her secret is discovered by her classmate Natsuhiko, who then confesses his own kink: he's a narcissist who has to wear coke-bottle glasses to keep himself from obsessing over his image in any mirrored surface. The two soon bond over their kinky lifestyles, but their tenuous relationship is threatened when a popular boy also discovers Mitsuru's kinky little secret.
