Deciding they can’t just hole up at Natsuo’s friend’s house, Natsuo and Rui spend the better part of half this episode stalking Hina, but coming up with absolutely nothing. They even steal her phone while she’s in the bath so Rui can try to imitate her sister’s voice and break up with Shuu. It all fails. But then something fortuitous happens: Hina and Shuu come to them, at the very cafe where Natsuo’s friend works and where Natsuo and Rui are discussing their next steps.
Things accelerate quickly, as Natsuo comes right out and demands Shuu end it. Shuu is non-committal, and when he tells Hina he still needs more time before he can divorce his wife, Rui throws a glass of water in Shuu’s face and runs off. Natsuo catches up to her, to be a shoulder to cry on. This whole process of confronting Hina’s affair has definitely brought Natsuo and Rui closer together. Neither of them are happy with how things turned out, and both are in agreement that they want Shuu out of the picture.
Ultimately, however, it’s up to Hina to make the choice. Shuu seems fine with the status quo being maintained indefinitely, where he’s with both women and doesn’t have to take responsibility one way or the other. The next morning, Rui’s eyes are puffy from crying all night, and doesn’t speak to Hina when she suggests they go shopping together for a birthday gift for their mom.
Natsuo, meanwhile, is off to visit his mother’s grave. We get a flashback to ten years ago: Natsuo was in first grade, and a crybaby. Worried about, well, worrying his mom once she passes away, he resolves not to cry, even at the funeral where it’s expected. He wishes she were still alive, and wonders how life would be if that were so.
Then he’s surprised to find Hina and Rui join him at the grave. They’ve come to formally introduce themselves to his mom and give offerings. Hina also informs Natsuo that she’s broken up with Shuu. Natsuo is delighted, and Rui is beaming. Hina even says she’s been thinking about doing it anyway due to Shuu’s half-year-long reluctance to leave his wife.
What stopped her from leaving him was her genuine love for him…but ultimately family came first. She couldn’t go on with Shuu knowing it made them so unhappy. The show seems to be taking Natsuo and Rui’s side in this instance, but will things really be that simple as Hina pulling the plug? And what of Shuu’s observation that Hina doesn’t seem to treat Natsuo like a kid? I forsee more potholes on the road of familial bliss. This is a drama, after all—not…some kind of…“constantly happy times-having” show…
