It's Either The Three Of Us, Or None Of Us
This show was such a fun and sweet experience. I genuinely looked forward to it every week, I liked these three weirdos and their chaotic softness.The premise is kind of wild in the best way, it starts off with a child narrator talking about Takuzo, a lonely guy who’s starting to think about marriage. Then there’s Mia, his ex, now dating a younger dancer named Shinpei. Things get interesting when the two attend a lesbian wedding, and Shinpei just casually suggests, “Hey, what if the three of us got married?”
At first, Mia’s thrown off (understandably), and instead of confronting it directly, she takes her boyfriend to her ex’s place, hoping it’ll stir some jealousy and kill the idea. But surprise, Shinpei and Takuzo actually hit it off. Not even a hint of rivalry. They get along so well it catches Mia off guard.
The sweet twist early on is that the child narrator turns out to be Pakhun, the pet rabbit Mia and Takuzo raised when they were dating. He’s been watching over them from rabbit heaven this whole time. That reveal mid-ep 1 was such a funny, touching moment and instantly made me love the tone the show was going for.
Throughout the episodes, we slowly unpack each character, we got some focus on Takuzo, his past, his insecurities, and his lingering feelings for Mia. We meet Sayo, a co-worker who shares his random hobby of building Lego cities. She believes in platonic friendship between men and women, but the show teases her as a love rival. Honestly, I wish they’d kept her strictly as a friend. The trio dynamic was strong enough, and her romance subplot felt unnecessary.
One of the highlights for me was how the show portrayed the trio relationship. It had its ups and downs, but it wasn’t over-dramatized. The three of them actually talk, support each other, and even argue in a realistic way. When Takuzo gets sick and Mia and Shinpei come over to take care of him, I was like okay, these three are already kind of living like a family. You can really feel how their connection grows, slowly and believably.
The final episodes bring everything together. There are a few emotional stumbles, some pushback from people around them, but nothing overly cruel or unrealistic. Even the mothers’ reactions were done well, shocked but not villainized. They take time to process, then try to support. It felt grounded.
And the ending was So cute. The trio basically says: it’s either the three of us or none of us. And they actually go through with the marriage. The show doesn’t treat it as a joke or phase, it gives them a real, soft, happy ending.
My only real critique is that while the show depicts a poly relationship, it doesn’t feel like it was written by someone who’s poly or queer. There’s a slight outsider lens, like it’s more of a thought experiment than something personal. It’s respectful, yes, but not quite as layered or lived-in as it could’ve been.
Still, overall, Sannin Fufu was a warm, charming, and refreshingly odd little gem. It didn’t always hit super deep, but it knew what it was doing: telling a story about people figuring out how to love each other in a way that works for them. And that’s honestly enough.

A rabbid who is happy with a poly relatiosship...
It's unusual that a series/movie explore a poly relationsship. The only question I always agreed with is: Why is marriage only for two people? This is something I still don't understand, because if you are three or four people so many things in life, especially the painful stuff would be so much easier to deal with. As that may be, it was refreshing to see that in a series. While it was intersting to watch, I feel the story is in part superficial, especially the sexual aspect. While the older of the two man give me much more "gay" vibes he is the one first opposed, That did not really match for me. Also I wished there would have been more intimate moments where the three explore each other, because if that part does not work, the relationsship part would not work either imho.I also understand why this is a comedy setting, but I would have prefered if this would have been filmed in a much more serious way, But I also understand why they did this, because things beside the social norm in Japan are hard to do and I assume they wanted the viewers at home not to feel offended.
Even with the negatives, I had a lot of fun watching this and the ending is hinting a season 2 which would be so much more interesting... As usual japanese productions bring something unusal on the screen and for that I appreciate it a lot. If you prefer it light-hearted and not so heavy, you should watch it. Thanks to my friend Daniel who showed me this show, otherwise I would not have noticed it :)
