One day, a sudden kiss ignites a thirst that had been suppressed. A mark is engraved on the slender arm of Akari, a girl who always stays in the nurse's office away from the classroom. Kanna, a married teacher, has a bruise hidden beneath the long sleeves she always wears. As they lick each other's wounds, even the pain in their hearts begins to erode. A warmth that cannot be called love, an attachment that cannot be called healing. Lips and fingertips meet as if embracing each other. Akari's feelings shake Kanna, and before long, the two of them sink sweetly into that darkness. "I can't live without you" - these words further ignite the fire of desire. A maddeningly beautiful codependent lesbian drama about two women who fall into each other's pain.
