Ririna doesn’t simply say she’s willing to abandon their arranged marriage for Yukari and Misaki’s sake; she lays out in a very detailed and realistic way exactly the way it’s going to happen, and it involves her and Yukari pretending like they hate each other’s guts—in other words, lying.
Yukari doesn’t like the sound of that one bit, as he doesn’t want to even pretend he doesn’t like Ririna. But Ririna appeals to Yukari’s deep and inspiring love for Misaki—without which Ririna would never have come out of her shell—and is able to get him to agree to her plan.
That means, at some point, if all goes as planned, Ririna will have herself “recalculated” to find another partner to marry, and asks Yukari to ‘show her what to do’, so to speak. The practical excuse aside, both Ririna and Yukari are lying here as well.
Ririna loves both Misaki and Yukari, so she doesn’t want to hurt either. What she fails to realize is that Misaki and Yukari have the same exact reason they don’t want to hurt her: they love her too. Forget about levels or tenure; love is love, and especially during one’s youth it can be extremely hard to distinguish one form for another.
As a result, Yukari initially stays away from the wedding dress fitting, convinced he’s hurt both Ririna (by agreeing to her plan) and Misaki (by kissing her in the chapel), and not wanting to cause any more pain to either. Nisaka shows up and lays it out as only Nisaka can: people who are hurt by loving him is not his problem; it’s theirs.
Nisaka speaks from experience here; he knows he’ll never have Yukari or even get him to look at him the way he wants…but he’s not going to bother him about it. He tells Yukari that when it comes to love, you have to look out for number one.
In Yukari’s case, he doesn’t feel comfortable living life without Misaki or Ririna. At the chapel, Misaki assures Ririna that her plan is impossible, because she, Misaki, loves both Ririna and Yukari. She couldn’t let Ririna drop her marriage to Yukari any more than Yukari or Ririna wanted to hurt Misaki by getting married.
It’s quite the conundrum! And certainly one for which there are no long-term answers. Presumably, Ririna and Yukari will one day marry, just as Misaki will marry her match (we finally learn definitively that she hasn’t received her notice yet). It would seem that love is not a problem for any of the three; it’s just a matter of learning what kind of love that is, and how that will (or won’t) jibe with cultural and societal norms.
Is this finale a cop-out that lets everyone off the hook by delaying a concrete decision on who marries whom? Sure is. But I asked for someone to win last week, and it would seem that, for now at least, everyone wins…Except Nisaka!
