This is a work filled with the bittersweetness of youth. Having actually experienced the 'Inside the Locker' series starring Konatsu Kashiwagi, the storyline starting from the love letter incident in the classroom is youth itself. The scenario where the protagonist hides in a cleaning supply locker and is discovered by Konatsu offers a sense of reality while providing a dreamlike time.

Konatsu Kashiwagi's greatest charm is undoubtedly her innocent and cute appearance. Her somewhat rustic, plain looks may divide opinions, but the JK uniform suits her well, evoking a familiarity as if she could really be a classmate. Her body is soft and plump, with large breasts and a curvaceous figure that excites many fans; those who like the lolita type will adore her face.

The close-contact scenes inside the locker are the highlight of this work, and the sense of proximity itself is highly commendable. The girl's petite stature stands out, and the close-range interactions make the heart race. However, if one seeks eroticism, it might feel slightly lacking. There is less playful intimacy, and the stimulation as an adult VR is relatively restrained. In terms of camera angles and perspectives, some parts feel monotonous, and the constraints of the limited locker space are undeniable.

In terms of story, the development where the situation turns into mutual love through the love letter is interesting. The reversal of what would normally be considered perverted is refreshing and elicits laughter. The first half features play inside the locker, while the latter half has more splash scenes after exiting, offering varied enjoyment.

Overall, it is recommended for those who want to savor cuteness and the atmosphere of youth. If you prioritize pure love elements over eroticism, it could easily score full marks. This series has an appeal that makes you want to collect all of it.
