Watashi no Otto wa Reitouko ni Nemutte Iru

Kisaragi Nana, who lived quietly in a suburban house while earning a living at an online shop that handles imported furniture and miscellaneous goods, lives with her fiance Sato Ryo. However, Ryo suddenly changes and becomes violent. Afterwards, she strangles Ryo who is in a tipsy state. She hides the corpse in an old freezer in the storeroom and her free life would soon begin...

Her fiance, Ryo, whom she killed, is somehow alive. But his corpse remains frozen in the freezer. "It's not enough to just kill." Natsuna thinks and begins chopping off a part of the corpse. She comes up with a terrifying idea to feed it to Ryo, who has revived. However, Ryo seems to have changed and says he will get a job. Not fooled by his words, she packs him a hamburger she prepared in the middle of the night and gives it to Ryo who is going for an interview. Immediately after he goes out, Kujaku, who lives across the street, greets them. She tells them she wants to relax. Although Nana allows her in, she isn't interested in conversing with her. However, Kujaku brings over a cake from the bakery where Nana had met Ryo six months ago. She recalls the memories of that day...

Nana stopped Ryo from trying to open the freezer. She puts a cloth over it so she can't see its contents. After she places a rabbit figurine on it as a weight, she gets a call from work and leaves. On the way, she remembers she forgot to lock the warehouse and rushes home. When she looked inside, the figurine hadn't been moved. Later, Ryo prepares a meatball cream stew made from homemade minced meat and tells Nana he invited over the President of the company he works for...

Nana is taken by Ryo who says "let's check the inside of the warehouse together". One the other hand, her mother, Konome, is informed that Sato Ryo is pseudonym of Kubota Sou and he has a criminal record. Worried, Konome tries to contact Nana. Unable to get in touch, she calls Kujaku and asks her to go over. Kujaku goes over to Nana's house and asks Ryo a particular question...

When Kisaragi Konome hears that Sato Ryo is actually Kanade Sou, she rushes over to protect Nana. She winds up stabbing Ryo with a knife. Nana tells her that Ryo and Sou are twin brothers but Konome refuses to listen. Fortunately, due to Kujaku's quick thinking, Ryo is okay. As proof of him being a twin, Nana shows Konome the corpse in the freezer that has the same face as him and reveals what she did and why.
