Harada Izumi has just transferred to a new high school and is doing her best to fit in, which isn’t easy when you have a secret as big as hers – that she can read minds! And it doesn’t help when she is seated next to Akechi Kikumaru, a handsome young man she immediately takes an interest in who is more than a little bit of a pervert!

Marimo Himenogi desperately wants to become an idol singer. When a local contest is announced, she begs her boyfriend, Ayumi to sing as her partner. Ayumi relents, and disguises himself as a girl so that he and Marimo can enter the singing competition. Surprisingly, they win and are signed to a recording contract as a new group called "Twinkle". Now they must keep their newfound fans from finding out that Ayumi is actually a boy.
