Hanazono No Kioku花园的记忆; 花園の記憶; Kuroneko to Futari Kurashi; Memory of a Flower Garden

From Hoshi Kuzuu: Chris, a beautiful young man whom he met at a bar and Yuu, who had a drunken marriage with him. And the matching tattoo on his ring finger was also meant as a joke... “We're married, so we've gotta stay together.” Persistent and possessive, he uncovers everything about Yuu's past. They happily drown in that drunken passion, but...!? A troubled tale of love that will move you to tears...has been drawn! • Kuroneko to Futari Kurashi (Black Cat and the Domestic Life)
