First-year high school student Saki is head-over-heels for her the older Makoto. After all, this senpai is tall, beautiful, and oh-so-cool... Who wouldn’t fall for a girl like her? The bright and bubbly Saki doesn't hesitate to confess her feelings. But Makoto turns her down, because Makoto isn’t a girl, but rather a cross-dressing boy!

Second-year Makoto is used to the negatives that come with his love of cross-dressing: harsh gossip from his classmates, the disapproval of his mother... Most of his classmates already know, but still, when he tells Saki, he expects her to be disgusted. Yet Saki's feelings only grow stronger, and she says she doesn’t care about Makoto's gender expression. In fact, she's determined to win him over and become his first love!

Caught between the straightforward Saki and his overly protective childhood friend Ryuji--who may have feelings for Makoto of his own--Makoto must navigate a complicated love triangle and chart his own course to happiness.
