Out of sight, out of mind!
Bunny girls do not live in libraries. This is simply common sense. And yet, that's exactly where Sakuta finds one in the wild. More bewildering is who the bunny girl is: Mai Sakurajima, a girl one year older than Sakuta, famous at their school for her acting career even though she's currently on break. To top it all off, it seems like no one else in the library can see Mai at all, no matter what she does or...wears. Wanting to find out more about this mystery and maybe get a little closer to this beautiful upperclassman in the process, Sakuta launches an investigation to discover why an unforgettable bunny girl keeps becoming totally invisible.
How far can a fake relationship go?
Mai is no longer invisible--she's acting again, and she finally said yes when Sakuta asked her out for the millionth time. Life couldn't be better for Sakuta...until he wakes up and finds himself reliving the morning before she agreed to date him!
Assuming this weird time slip to be another case of Adolescence Syndrome, Sakuta begins searching for clues and stumbles upon the first-year Tomoe. Though the last time they saw each other involved getting kicked in the butt, now she's desperately trying to avoid getting asked out by the boy her friend is crushing on so she won't be ostracized. One ruse leads to another, and soon news spreads that Sakuta is Tomoe's boyfriend. Now how is he going to explain this to Mai...?
