Kido Tatsuhiko arrives in Tokyo to pursue his art school dreams, setting up in a modest apartment that comes with an unexpected feature: a small hole puncturing the wall between his room and his neighbor's. What starts as idle curiosity transforms into something far more complicated when he discovers Ikuno Emiru on the other side, a girl with unabashed voyeuristic interests who pulls him directly into her world. After an embarrassing mix-up leaves her holding a photo that makes him look like a pervert, she uses it to pressure him into keeping the gap in the wall open, and he soon finds she studies at his school too. What neither of them anticipates is how their arrangement spirals beyond the initial transgression, pulling both deeper into territory neither fully controls. The single OVA mixes comedy, drama, romance and ecchi, and it came packaged with the limited edition of the manga's thirteenth and last volume.
