A girl so obsessed with losing her virginity that she's paralyzed by the thought of anyone actually seeing her. The show treats this contradiction, desperate horniness meeting absolute terror, as genuinely funny instead of punching down. Yamada's neurosis isn't the joke; her commitment to solving it while pretending she has it all figured out is, and that precision makes every awkward conversation land.
Yamada arrives at Takizawa High School with a singular mission: lose her virginity to one hundred men before graduation. The catch? She's convinced her body is flawed and terrified an experienced partner will judge her. Her solution is ruthlessly pragmatic: find another virgin who won't know the difference, seduce him, build confidence, then move on to the next target. Enter Kosuda Takashi, an oblivious classmate who becomes the unwitting centerpiece of her plan. What Yamada doesn't anticipate is her complete lack of seduction skills. Her attempts at flirtation range from painfully awkward to spectacularly backfiring. Meanwhile, Kosuda remains blissfully unaware of her intentions while simultaneously developing genuine feelings for her. The result is a comedy that thrives on miscommunication and escalating desperation. Yamada's aggressive pursuit keeps crashing against reality, forcing her to actually interact with Kosuda as a person rather than a stepping stone. What begins as a transactional scheme gradually becomes something messier and more genuine than either of them anticipated. Fast-paced, frequently crude, and surprisingly invested in its characters' emotional growth beneath the surface chaos.
