The long-awaited hot spring trip of Kasumi, a 26-year-old married woman, was something I splurged on by buying the 4K version, but the video quality didn't quite meet expectations, which was a bit disappointing. Indeed, it lacked the realism where pores are clearly visible, as seen in the 4K version of Tsukino Kasumi's 'The Naked Housekeeper', giving off a somewhat blurry and flat impression. It felt like a filter was applied, making me think the HD version might have sufficed. That said, Kasumi's devilish charm, along with her face, voice, and gestures that drive men crazy, remains intact, and the theme of 'wanting to go crazy over a lover' was thoroughly enjoyable. For fans looking to experience a night dyed with infinite teasing and ecstasy, this is still a must-watch.
