i want to reread it xd

Guys, can someone send me the title of this manga I read a long time ago? It's about a girl who got kidnapped by a stalker, bla bla. The stalker was smelling the girl's used period pads, and I remember the house the girl was kidnapped in was a mess, bla bla. The boy's arms were cut off and his legs, and reverse card, that boy was hiding inside the girl's apartment with her boyfriend (not the stalker, as in another man) while keeping the stalker inside the basement, and the girl was just showering and treating the stalker like an animal.
