First thing to understand is that this is a continuation of a Spring 2019 series, so before diving into this I’d advise watching the first season, my mostly-glowing reviews for which you can find here.
For those who are all caught up, BokuBen 2 offers more of the same vibrant brand of ecchi-related misunderstandings between various girls and their well-meaning male tutor and friend which inherently get in the way of the tutoring, hence the English title We Never Learn!
This week, Yuiga Nariyuki spends the most one-on-one time with Ogata Rizu, in which the first such misunderstanding is a mix-up between test scores and cup sizes. Since the worst test score is an E and Rizu is well beyond E in cup size, the wording of Nariyuki’s earnest attempts to encourage her (“There’s room for growth!” “I know how you feel!” “Let’s both grasp what we want!”) only serve to reinforce Kominami Asumi’s claim that Nariyuki is a “secret horndog.”
Nonetheless, Rizu believes she’s the one being immature about this, and that there’s nothing wrong with a boy she likes admiring her chest. Nariyuki is a half-beat too late in their conversation to clear things up, as Rizu finally offers to let him touch them “for only a second” just as her beastly father arrives at their booth.
The next segment involves Nariyuki in a group study session at a cram camp called “the Getting Inn” (not suggestive at all!) with his three tutees plus Asumi, when Fumino accidentally slips up and calls him by his given name, like she did when they had to get a hotel room together and pretended to be siblings.
Rather than reprimand Fumino (or think a little longer about why she called him Nariyuki), Takemoto Uruka wants in, and won’t respond to Nariyuki until he calls her Uruka. She also insists Rizu start calling her Uruka. As with Fumino going back to Yuiga before slipping up here, who knows if the given name-calling will continue, but the fact it’s not an unthinkable concept shows growth among the friends.
Things get a lot more intimate between Nariyuki when his three primary tutees when they head into the hot spring bath early, just before the men and women signs are changed. When Nariyuki heads in, he believes, correctly, that he’s in the men’s bath when he encounters a nude Fumino washing her hair.
Once the three realize they’re in the wrong, they prepare to skink away, but are blocked by the arrival of three more boys who most certainly are horndogs. Thankfully, they’re sufficiently distracted by their own attempts to widen the bamboo in order see into the women’s bath that the girls are able to escape into the steam, while Asumi on the other side jabs her fingers into one of the peeping tom’s eyes.
Once everyone is dressed, the girls thank Nariyuki for being a gentleman about things, but he must torpedo the goodwill by presenting Fumino with the bra she left in the changing area. The implication is that he knew it was hers due to the cup size, expressed through a very unexpected but appreciated parody of the touching ending shot of Nausicaä of the Valley of the Wind.
