Irido Yume and Irido Mizuto dated in junior high, and apparently had a pretty rough breakup. Now, due to their mom and dad marrying one another, they are now stepsiblings. Naturally, their folks don’t know about their history, so Yume and Mizuto have to hide how much they loathe each other, and settle for trading barbs outside of said folks’ earshot. Already, I love it. It’s so awkward, and somewhat tawdry. I wouldn’t wish this fate on anyone!
But here’s what really makes Tsurekano interesting: as they spend more and more time together—and they can’t not, as they not only live under the same roof, but are in the same class at the same school—they both learn in just this first episode that those old feelings they once had for one another don’t take much to resurface. Yume claims the class rep mantle and gains a lot of friends fast (never her forte in the past), but it backfires when guys try to befriend Mizuto to use him as a stepping stone to ask her out.
Back home, Mizuto doesn’t let Yume express any pity for him, or even say what’s on her mind, but it’s clear it bothers her that what she did might’ve ended up hurting him. Just because you’re exes doesn’t mean you automatically stop having feelings for each other, even a sense of wanting to protect the other. She overcompensates the next day by clinging to Mizuto and saying she has a brother complex, and after Mizuto makes them supper when their folks are out, she remembers the feel of his shoulder and tries to deflect by demanding he forget.
Frustrated by how passive he’s being (and has always been), Yume finally decides to get a literal rise out of him by striding into the living room in a tiny, tightly-wrapped towel and nothing else. While he is indeed initially flustered, her victory is brief, as the towel starts to loosen. Rather than do anything brazen, he covers her up with his hoodie, knowing she didn’t think this plan through. He just knows her too well. They both know each other too well.
And because both Yume and Mizuto are in a rom-com anime, it was inevitable that one of them would slip and fall towards the other, leading to a compromising—but also familiar—position. Mizuto even calls Yume by her old name, Ayai, as he brushes her bangs back in preparation for a kiss that is really only interrupted by the sudden arrival of their parents. Yume’s lucky there’s storage in the couch they were on.
But let’s assume these two are done and done for good because they are now stepsiblings. The show has many places to go with this, from exploring how they’ll no doubt stumble and fall again into old patterns from when they dated, to how they’ll try to counter that by entering hostility-regret-truce spirals, to the underlying mystery of why they broke up.
I also loved the detail that they were both shy “nerds” who still have rooms packed with books, and are both at the top of their class. Oh, and most important: while there are times that I’m on Team No One, at the end of the day both Yume and Mizuto want to make sure their parents are happy. They’re good kids, and I look forward to watching them navigate this strange new normal.
