one day, an unexpected kiss lit a fire to the thirst that had been sealed away. the scars engraved on the slender arms of akari, a girl who is always in the infirmary, away from the classroom. the bruises of kanna, a married teacher, hidden under the long sleeves she always wears. licking those wounds, even eroding each other's pain. warmth that cannot be called love, attachment that cannot be called healing. lips and fingertips overlapping as if embracing. akari's feelings shake kanna, and eventually the two sweetly sink into that darkness. "i can't live without you" - even those words ignite desire. a madly beautiful codependent lesbian drama of two people falling into each other's pain.
