Suzuki Tadashi is a gloomy, lazy guy working at a bottom-tier publisher.
Out of nowhere, he gets a super smart and gorgeous girlfriend: Mizuho Hakozaki.
He tries his best to be the kind of man who deserves her, but everything backfires.
A tragic death comes for Tadashi... or so it seems...
But then he wakes up as his own girlfriend—he's become Mizuho Hakozaki!
