Futaba initially thought she’d be going on a trip to the beach with just Sakurai and her brother Yuuto, but Sakurai also invites Kazama (of course), Takeda, and Natsumi to make things more “fun”…which is to say, more interesting. What results is the two core couples having a blast together, with the added thrill of showing more skin.
As expected, Takeda is a mountain carved out of granite, but it’s to the show’s credit Futaba doesn’t show up in a school one-piece, but a cute polka-dot halter/skirt combo. While towing her really far from the shore, then teaching her to swim, Takeda makes it clear her outer characteristics aren’t as important to him as how hard-working and kind she is on the inside. At the same time, he says she looks cute.
After a day working up an appetite on the beach, the group heads to the inn for a sumptuous feast where Futaba fills Takeda’s oft-empty rice bowl, but shushes him when he talks about Futaba’s cooking. Clearly, he availed himself of her offer to make him Hamburger Steak. Meanwhile, fifth wheel Natsumi keeps herself entertained by watching Futaba and Takeda get along and making sure Yuuto, the only kid there, gets some attention.
That night, after fireworks, Sakurai and Natsumi try to get Futaba to admit that things are “going well” with Takeda, considering how close they are, but Futaba, embarrassed, just wants to sleep. Meanwhile their room is close enough to the guys’ that Kazama can hear them, and between that and Takeda’s snoring, doesn’t get any sleep. That morning, he and Futaba eavesdrop on Takeda and Sakurai talking about them in a way that makes their ears red.
On their last day on the beach, Kazama is too fatigued for more activities, so Sakurai stays with him under the umbrella, then suggests they head to a konbini for drinks. She also picks up an ice cream, and when it reminds Kazama of old times, she offers him a sip, which is really offering him an indirect kiss. He declines, but Sakurai, knowing Kazama well, had a second ice cream just for him.
As the sun gets low, Takeda and Futaba end up tiring themselves out to the point the latter is curled up on the arm of the former, giving their friends an opportunity to document with photos how close they truly are. Those photos probably aren’t 100% okay with the HR department, but then again they aren’t in the workplace. Besides, Sakurai and Kazama don’t mean any harm. They’re happy to see their co-workers happy.
The next morning back at work, Futaba is embarrassed to reveal how tanned she got at the beach, having previously been accustomed to being shaded by her gramps’ umbrella. When Takeda arrives just as tanned, it confirms to the whole office that these two had a lot of fun together on their summer break. That said, with both Takeda and Futaba intent on maintaining that they’re merely “senpai and kohai”, who knows if anything further will come of it than what we’ve got…which really isn’t so bad!
