Just as the title says, I can’t remember the title of this one manga I read some years ago and I’ve been thinking about it recently.
It’s a schoolgirl comedy where the main character gets a fairy godmother to spur her on. The fairy godmother to get her to confess to her friend, places a curse where the whole world will blow up if she fails. I can’t remember the names of the characters, but I remember the main character dressed somewhat sporty, wearing sneakers, and her best friend confessed that she did love her but was too much of a bottom to ever confess first. And the fairy godmother at one point said she was divorced.
