In Case of My Death, Blame Cupid (and Also Yumeko Kawamoto)

Kira Timurov-rich, ruthless, possibly allergic to normal human emotion-tries to write a normal love letter to her crush, Yumeko Kawamoto.

Unfortunately, her definition of "normal" includes fake deaths, suspicious perfume, and a suspiciously flammable envelope.

Somehow, instead of getting expelled (or exorcised), she ends up with a kiss, a girlfriend, and a growing list of crimes against romance.
