She writes of her feelings for him in the journal she kept all her life; in most variations of the story, Takeo ends up finding and reading her diary. He becomes obsessed with the idea that Kayako is cheating on him with his son's teacher – or worse, Toshio could not be his son, but Kobayashi's. When she gets home that day, he violently attacks her upstairs, pushing her against the wall. Toshio is in his bedroom drawing and hears the noise and, coming outside, watches the violence which is occurring below through the banisters. Kayako tries to run away while Takeo chases her, but he pushes her down. She sprains her ankle, stumbles, and falls, and has to go down their house stairs by crawling. After much effort, she makes it to the front door, only to find Takeo slowly walking behind her, watching her suffer. He then snaps her neck to a 90-degree angle and crushes her throat, takes her to their bedroom and puts her in a trash bag. Kayako is still alive, but paralyzed, capable only of letting out a croaking moan. Takeo stabs her multiple times (an event that is not shown explicitly in either "Ju-On: The Grudge" or "The Grudge", but heavily hinted at, as Takeo is shown lowering a box cutter to her face in the former, and dragging her bloody body in the latter). Then, he puts her body in the far corner of the attic, through an attic door in the ceiling of their bedroom closet.
