It’s bad enough that Fumino’s father fails to show up for parent-teacher conferences. It’s quite a bit worse when he does come to her school to court Rizu for her mathematical prowess, since he’s the professor at the open campus.
We learn he’s very much against Fumino’s dream to enter the sciences, calling it “the ignorant fantasy of an incompetent person” and saying she’s free to leave his house if she wants to pursue it. That’s when Nariyuki, already physically in the middle of this family squabble, says he’ll take Fumino into his house for now.
If Uruka was the protagonist last week, Fumi obviously fills that role here. She’s always worked to steer Nariyuki towards the two girls who have the strongest feelings for him (Uruka and Rizu) while undervaluing her own. Now we know why: since her mom died, she’s never felt like she’s measured up.
That’s why I’m so glad to see that circumstances conspired to bring her closer to Nariyuki than anyone else, almost as a challenge to her insistence on putting herself third (or worse) in the running. The two once had to share a hotel room together, which led to one of the more poignant moments of the series.
Now, with the endorsement of his mom (who adores Fumi) and the disapproval of his little sis (who may only ever consider herself worthy of him), Fumi becomes a temporary member of the Nariyuki household. That warmth and familiarity is echoed in a scene where the two are brushing their teeth together, and both note (Fumi in her head, Nariyuki aloud) that it’s like they’re newlyweds.
Despite Uruka being his childhood friend, her feelings are so intense that situations like the ones he shares with Fumi could never be possible without her quickly overheating. Fumino, who always tries to keep Nariyuki at a romantic remove, slips into domestic bliss as easily as Uruka swims a lap.
While studying together as the rest of the family sleeps, Fumino tells Nariyuki that her mother was a famous mathematician whom her father placed on the highest of pedestals. When she suddenly died, his grief was so great that he’d sooner slap Fumi across the face—and stop even looking directly at her—rather than properly deal with the fact his wife was gone.
Instead, Fumi’s face was a constant reminder of what he lost, and her attempts to “do math” in her stead only made him more bitter and angry. Sorry you lost your wife, dude, but that’s no excuse to be a complete and utter SHITHEAD to your precious only daughter!
While hiding (in very close quarters) from her dad after he came home unexpectedly (they were there to pick up *some* of her clothes), Fumino finds her mother’s laptop, which contains her password-encrypted thesis. I’d bet the password is “FUMINO” but because it’s that, her father never managed to unlock it.
But Fumino’s done feeling bad for her father for shit that wasn’t her fault. If she can only pursue her dream by leaving him and her home, so be it. It may not be the safest or most practical route, and all too easily dismissed as impulsive youthful rebelliousness, but…let’s not forget: her dad is a diiiiick.
