Shimizu Mayu mysteriously lost her memory after taking a nap. She had to learn about herself from other people.
One day, she discovered her true identity: an absolutely terrible woman.
She loved everyone and cast her net wide, with so many ex-boyfriends it was downright appalling.
She went to buy a cup of coffee, and the dark-skinned barista turned out to be an ex-boyfriend.
She moved to a new place, and the bespectacled graduate student next door was an ex-boyfriend.
Then, after she was kidnapped in an accident, she met the story's big villain, who came to rescue her. He seemed to be one too...
He was cold and left her with just one line: "Remember, my name is Gin. Don't laughably think you can get away from me just because you've lost your memory."
Shimizu Mayu was utterly confused. This was another ex-boyfriend of hers.
She began to question her life. Had she really been so amazing before, with so many ex-boyfriends?
Every single one of them was top quality.
Later, a group of ex-boyfriends gathered and started fighting with weapons, battling to the death.
Just as Shimizu Mayu smugly assumed they were fighting over her, one of them said, "Have you guys gotten addicted to pretending to be her ex-boyfriends?"
Shimizu Mayu: "…"
Well, well. They'd all been putting on an act for her.
Shimizu Mayu stormed off in a rage.
A few months later, the bespectacled graduate student confessed to her, saying he wanted to get back together.
Shimizu Mayu already knew the truth, so she coolly turned him down without a second thought.
Then she turned around and ran into her dark-skinned ex-boyfriend. Before she could do anything, ex-boyfriend number who-knows-what, whose name she didn't even know, came over from a distance.
The scene was all too familiar. Shimizu Mayu bolted without a second thought.
Inner monologue: Ah! Please, just leave me alone!
Later.
Shimizu Mayu: "So it's all about acting skills, is it? Let's see who can outdo whom.
She struck a pose and memorized her line. "Hey, handsome, wanna hook up?"
With her face painted like a ghost and bright red lipstick, Shimizu Mayu shot the dark-skinned man a sexy (terrifying) wink.
Dark-skinned undercover agent: "..."
