This work is a standout piece that leverages 4K filming and binaural recording to deliver an overwhelming sense of immersion. The charming and erotic 'miru' acts like a real girlfriend, whispering sweetly, 'Promise you won't masturbate alone!' while fully managing the viewer's ejaculation, a novel concept that shines brightly.

'miru's appeal lies in her constant smile and her skillful teasing that blends潜在的なeroticism. The work features a rich variety of play, from 'Not yet!' delays to 'Cum in 10 seconds!' countdowns, making viewers feel as if they're completely under her spell. Scenes where she says, 'My pussy feels better than your hand, right?' while allowing unrestricted penetration are sure to captivate audiences.

The immersion as a first-person perspective work is exceptional, with gameplay unfolding entirely from the male actor's viewpoint. Although not a VR title, using headphones enhances the realism significantly. However, scenes where the male actor waves hands or makes gestures during climax can break the immersion, an area for potential improvement in future works.

The performance by actress 'miru' is top-notch, fully utilizing her adorable looks and erotic aura. The scene where she gazes and says, 'Cum while looking at my face,' is highly recommended for face-fetish enthusiasts. The 4K high definition captures subtle changes in her expression, underscoring the work's high quality.

Personally, though brief, 'miru's masturbation scene is memorable, leaving one amazed that anyone could hold back in such a situation. In reality, being told 'You can only ejaculate in front of me!'—especially by such a cute actress—would be irresistible for most.

With a recent trend where full first-person perspective works are mostly shifting to VR, this piece holds significant value as a rare non-VR subjective work. A series adaptation is eagerly anticipated, and its future developments are worth watching closely.
