The first minutes of this episode of Tada-kun are, in a word, heartbreaking. A grown Mitsuyoshi and Yui pray at their parents’ grave with their gramps, and we’re taken back to the rainy day their dad suddenly has to hop on a flight, and their mom drives him to the airport.
As they pull away, his dad pokes his head out the window and snaps a picture of his kids. Mitsuyoshi is sullen. Yui is cheerful. It turns out to be the last picture their dad took; he and their mom were killed in an accident, and would never return.
Back in the present, Kaoru blasts into the Tadas’ cafe to announce the “Tenth Annual Ijuuin Kaoru Show” is on, and it’s live. This year, all are welcome, from Hajime, Hinako and Yamashita Dog, to newcomers Teresa and Alec. Kaoru asks them all to sit back while he utilizes his not inconsiderable culinary skillz to prepare all their favorite dishes.
When Mitsuyoshi and Teresa are tasked with putting some food away in the fridge in the upstairs apartment, she’s drawn to that last photo Mitsuyoshi’s dad took, and when he explains the context, she remembers when she fell in the drink and was saved by Alec around the same time Mitsu and Yui lost their folks. She considers both times when they decided they had to try to become stronger; in her case for Alec’s sake; in his case for Yui’s.
The exchange is interrupted when Kaoru announces he’s completed everyone’s dishes and it’s time to dig in. Everyone agrees Kaoru (who comes from a restaurant family) is damn good at cooking, even if, in Alec’s case, she doesn’t outwardly say it. Instead, she merely polishes of every last bit of her katsu bowl and asks for seconds.
The Kaoru Show continues after dinner with a trip to a bathhouse he’s rented out for the evening (he’s a young man of means, after all), and the two genders split off to their respective sides of the bath. Since they’re in the bath, there is talk of boob size on both sides, as well as Yui thinking out loud that Teresa would be a great girlfriend for her big brother. Alec says Teresa already has one, only to dismiss it as a “joke.”
Over on the boys’ side, Yamashita pines for an “older girl” presumed to be Hinako, while Hajime overheats and slips on a bowl, nearly cracking his skull. When the two groups reunite, Hinako is right there by Hajime’s side to help him, for which he’s grateful, even if he told his friends in the bath that his getting romantically involved with her would never happen (likely because he’s still mostly convinced Hinako and HINA are different people).
After the bathhouse, the Tenth Annual Ijuuin Kaoru Show comes to a close, and we learn about it’s raison d’etre: ten years ago, when Mitsuyoshi lost his folks, Kaoru, who was his classmate but never got along with him before, took pity on Mitsuyoshi, and made cheering him up at any cost his life’s work from that point on.
In other words, or more accurately in Alec’s words, Kaoru is a “pest”, but “has some good points too”, one of them being he can always be relied on to cheer you up when you’re feeling low. He’s never failed to do so with Mitsuyoshi (and Yui!) for a decade and counting.
After everyone goes their seperate ways and the credits roll, we move on to an entirely new development: the arrival of Teresa’s apparent fiancee/suitor/betrothed, Charles, who not only can stop Alec’s attacks with one hand, but confirms that Teresa is not only a princess of “Larsenberg” (maybe not Luxembourg?), but its future queen.
That makes things a bit more complicated for her and Mitsuyoshi, now doesn’t it?
