Kawaii

What Kawaii is actually saying

The easy reading is that LE SSERAFIM made a cute Sanrio song. True. Also incomplete. Kawaii is not just describing an aesthetic. The song treats cuteness like a private rulebook. You decide what makes you feel good, what deserves affection and how much sweetness you are willing to show without apologizing for it.

That fits LE SSERAFIM better than it should. Their image is usually built around fearlessness, athletic choreography and a suspicious number of gym floors. Gen Hoshino does not erase that. He lets softness become another form of nerve. A woman can be ambitious, sweaty, stubborn and delighted by a tiny pink rabbit. Nobody explodes.

Song first: Gen Hoshino brought an actual song

The first gift is time. Kawaii runs nearly four minutes, which now feels like somebody left the studio door unlocked. The arrangement has room for verses, a chorus that settles into your brain and small instrumental details that do not have to sprint toward a dance challenge.

Hoshino builds the track from bright synths, springy rhythm and bass that keeps the sweetness from floating away. The groove is playful without becoming baby music. There is a slight oddness underneath it, the kind of cheerful sound that knows Kuromi is standing nearby with a skull on her hat.

The members do not have to shout over the production. Chaewon cuts through with her tidy pop precision. Yunjin adds shape and attitude. Sakura understands the Japanese-language phrasing and the wink inside the concept. Kazuha sounds increasingly comfortable in lighter material, while Eunchae gives the song the youthful bounce it needs without being asked to perform childhood.

The one thing I wanted

A stronger vocal left turn. The song is generous with length but surprisingly polite with its climax. One messy harmony pile, strange bridge or final-chorus detour would have made the ending feel earned instead of merely extended. I enjoyed the extra minute. I wanted it to misbehave once.

Official music video: Sanrio opened the toy box

The video connects the group with My Melody and Kuromi, the stop-motion stars of Netflix’s My Melody & Kuromi. Sanrio confirmed the collaboration as part of the series promotion. The characters are not random mascots pasted into the corner. They split the visual mood in two.

My Melody brings the soft pink domestic fantasy. Kuromi supplies black accents, mischief and the reminder that cute girls are allowed to be annoying on purpose. LE SSERAFIM move between both energies because the whole point is not choosing one acceptable version of femininity.

Small details worth pausing for

• The pink and black balance: My Melody and Kuromi keep the palette from becoming one uninterrupted strawberry milk commercial.
• Scale changes: Oversized props and miniature-looking rooms make the members feel as if they wandered into Sanrio’s stop-motion world without flattening them into cartoons.
• Costume logic: The styling borrows ribbons, soft textures and character colors while keeping each member recognizable. Nobody looks like she lost a fight with a mascot costume.
• The ending: The collaboration lands because the characters and the group finally share the same playful space. It feels like a meeting, not product placement waiting for its invoice.

The video director keeps the camera readable. That sounds basic, but K-pop videos have developed a habit of cutting choreography into decorative confetti. Here, the charm comes from letting the members react to the sets and characters. Cute needs facial timing. You cannot edit your way around that.

My actual first reaction

The full RaeRae take

I like Kawaii because it refuses the fake argument that a powerful girl group must graduate from cute things. LE SSERAFIM have already crawled across floors, kicked doors, survived public criticism and built entire choruses out of stubbornness. They do not lose credibility because My Melody arrives.

The song also understands that Japanese kawaii culture is not simply pastel decoration. It can include awkwardness, rebellion, comfort, collecting, self-expression and very serious adults spending irresponsible money on limited merchandise. Kuromi became globally popular because she lets cuteness keep its teeth.

Gen Hoshino was a smart choice. He writes pop that respects ordinary pleasure. He does not approach the group like a producer trying to prove he can make idols sound important. He gives them a warm, complete song and trusts the personality already there.

Is it LE SSERAFIM’s most daring single? No. It is a polished tie-in with a highly marketable character universe. I can see the machinery. I can also hear a good song inside it, which is where a lot of branded collaborations quietly fall apart.

Final verdict

Sweet, sly and much better constructed than it needed to be. Kawaii lets LE SSERAFIM wear ribbons without surrendering their spine. My Melody brought the invitation. Kuromi brought the emergency exit.
