My first thought about Mei’s Dad showing up is Please don’t be a creep. But once it’s clear he’s not, it’s also clear what else he’s not: Mei’s strict “sensei.” Mei’s ideal of her father is who he was, not who he is or who he’ll ever be again. He chose to leave the academy and won’t go back.
That decision left Mei alone on a path she thought they’d share forever. Her father’s absence has only made things worse, as by not opening his letters she could convince herself there was still hope he’d come back to that path.
Now that Yuzu knows the score from both sides, her goal of bringing the two together has gotten a lot more complicated. Mei is so distraught and fatalistic, she seeks an easy escape in fooling around with Yuzu. Yuzu is understandably insulted and pained if Mei thinks the only way Yuzu can “accept” her and “be the one that needs” her is to submit to commiseratory sex.
After an awkward morning where Mei slips out without breakfast, Yuzu’s Mama adds another piece to the puzzle: she calls her husband a “tsundere”, able to spread education and love to kids the world over, but finds it almost cripplingly difficult to do the same with his own natural daughter. And yet, he accepts that maybe he’s just not cut out for it, and that it might be too late, and asks Yuzu to be the support Mei needs in his stead.
While attempting to ascertain what Mei needs and how to support her, Yuzu gets some very welcome emotional and logistical support from Harumin, who strikes about the right balance between being almost too perfectly helpful and being a character in her own right.
When Yuzu gets word from Mama that Papa is leaving for abroad in less than two hours, Harumin takes Yuzu to school on her bike so she can find Mei, not wanting her dad to leave with things the way they are.
When they just miss each other in the chairman’s office, Yuzu hijacks the P.A. system to get a message to Mei: that she’s done a good job; that she shouldn’t blame herself anymore; that she’s pushed herself enough for someone else’s sake.
Yuzu snatches up Mei and they race to the station, which Mei thinks is another example of Yuzu acting without thinking. But Yuzu has thought about it a lot, and this is what she’s decided to do: cultivate a situation in which Mei is able to let go of “sensei”, embrace her father for who he is, choose her own path, and move forward.
They get to the station right on time to catch Mei’s dad. After they share some words, they have a cordial goodbye, and Mei actually calls him “father” for once. It’s certainly a bittersweet moment, but it also must be exciting and relieving for her; she really will inherit the academy, because it’s what she has decided to do.
That night, she opens and reads all of her father’s letters to her with Yuzu by her side. Yuzu is so relieved and happy that Mei has made so much progress that she can’t help but tear up a little. That, in turn, brings Mei’s face close enough to hers for a kiss, and they do kiss, but it’s not anything like any of the other kisses they’ve shared before. For one thing, neither forced it on the other.
With Mei’s daddy dilemma largely resolved, we immediately move on to this next stage in their relationship, just as Yuzu’s pink-haired, conniving, scheming, manipulative childhood friend remembers her and plans to “get back in touch”, which could well mean an attempt to ruin Yuzu’s life for her own amusement. Should be fun!
