Cactus's Secret Review: When the Girl Confesses First and Gets Called an Alien

I confessed to someone once, in middle school, and the boy laughed. He genuinely thought I was joking — that some friend had dared me to do it. I spent the rest of that year being extra cold to him so he'd never guess I'd meant it, which of course just made everything worse. So when I opened the first volume of Cactus's Secret and watched Miku Yamada get the exact same laugh, then get nicknamed "cactus" for going prickly every time her crush came near, I made a noise out loud. This was my exact teenage failure, drawn in Ribon's soft round lines.

That's the thing about this little four-volume series. It's not deep and it doesn't pretend to be. But Nana Haruta builds the whole story around something most shojo skips: the girl confesses first, gets rejected, and then has to keep showing up at school anyway.

Quick Take

• A shojo romance where the heroine makes the first move and gets crushed — then has to live with it
• Nana Haruta's comedy timing carries four breezy, complete volumes
• T (Teen) — gentle high school romance, nothing graphic

Story Overview

Miku Yamada has liked her classmate Kyohei Fujioka since middle school. When she finally works up the nerve to act on it, Kyohei is so oblivious he treats the whole thing as a gag. Worse, he starts calling her "cactus" — because whenever he's around, she gets defensive and prickly, all spines and no softness.

The first real gut-punch comes on Valentine's Day. Miku plans to hand Kyohei chocolate and confess for real. But Kyohei, having no idea he's the target, cheerfully volunteers to be her "practice partner" so she can rehearse her confession on him before the real thing. She confesses — to his face, meaning every word — and he rejects her, saying he only thinks of her as a friend.

That rejection is the engine of the series. Instead of disappearing, Miku has to keep sitting in the same classroom as the boy who just turned her down. The complication arrives in the form of Itsuki Natsukawa, the student council president, who witnesses how Kyohei treated her and decides to step in. His attention forces Kyohei to actually notice what he stands to lose. By chapter 12, the obliviousness finally breaks and Kyohei is the one confessing.

Characters

Miku Yamada — The reason this works. Miku is smart and stubborn, and after the rejection she doesn't curl into the whiny-doormat shape that shojo heroines so often take. She keeps her self-respect. Her arc is learning to stop being defensive — to put the spines down and let Kyohei actually see her — without pretending the rejection didn't hurt.

Kyohei Fujioka — A former delinquent type, and almost comically dense about feelings. The "cactus" nickname is his, and it's affectionate before he understands it's affectionate. His arc is slow realization: he doesn't dislike Miku, he just never processed what her prickliness meant, and watching someone else pursue her is what finally connects the wires.

Itsuki Natsukawa — The student council president and the romantic complication. He sees Kyohei reject Miku and takes matters into his own hands, becoming the rival who pressures the central pair forward. He's the catalyst that turns Kyohei's cluelessness into action.

What I Love About It

The "practice confession" scene. Miku has decided this is the day. She has the chocolate, she has the words. And Kyohei, with the best intentions and zero awareness, offers to let her rehearse on him — never realizing that the rehearsal is the real one. She says it to his actual face, and he pats it down as practice and then, separately, rejects her as a friend.

What I love is how cruel that is without anyone being cruel. Kyohei isn't a villain; he's just dense. Miku isn't pathetic; she did the brave thing and aimed straight. The comedy and the heartbreak are the same beat. Haruta gets that the worst rejections aren't the mean ones — they're the ones where the other person is being nice and still doesn't see you. That scene is why the "cactus" nickname lands: of course she goes prickly. She has to. It's the only armor she's got.

Memorable Scene ⚠️ Spoiler Warning

The reversal in chapter 12. After eleven chapters of Miku being the one reaching out and getting nothing back — after the rejection, after Natsukawa's interference, after Kyohei being clueless to the point of comedy — it's Kyohei who finally says it. The boy who couldn't tell a real confession from a practice run is the one who confesses.

It works because the series earned the inversion. The whole structure has been Miku doing the emotional labor; flipping it so Kyohei has to be vulnerable for once is the payoff. The cactus finally gets to lower her guard, because for the first time the other person reached first.

Pros & Cons

Pros

• The girl-confesses-first structure gives the rejection real weight
• Haruta's comedy timing is reliable
• Complete and self-contained at four volumes
• Miku keeps her dignity — no doormat heroine

Cons

• Short and light; the premise doesn't go anywhere unexpected
• Kyohei's denseness can test your patience
• A breezy read, not a deep one — if you want emotional complexity, this won't be it for you

Is Cactus's Secret Worth Reading?

If you want a short, complete shojo where the heroine makes the first move and the rejection actually costs something, yes. It's four volumes of warm Ribon comedy with one genuinely sharp idea at its center. If you're after depth or surprise, look elsewhere — this is comfort food, and it's good at being exactly that.
