Mihou and Ishin's cohabitation had started to settle into a routine, but lately, she's been coming home later and later, and her replies to messages have become fewer. Ishin begins to notice the growing emotional distance and slowly feels unease creeping in. Then one day, he accidentally sees a flirtatious email Mihou received from another man. After that, she stops responding altogether, returning home in the dead of night with the scent of cigarettes clinging to her. Overcome with jealousy, Ishin can no longer hold back—he pulls Mihou into a forceful embrace, covers her body with passionate love bites, and claims her completely, disciplining her in his own intense way...!
