HenSuki takes a break from Keiki’s Cinderella investigation to focus on his duties as Designated Cupid for Koharu and Shouma. After Keiki plays the third wheel, a double date is the next phase, with Keiki selecting Sayuki as the girl who’d least interfere with what they’re trying to do (Yuika might entice Shouma; Ayano might like his stink, and Mao won’t accept Shouma going out with a girl).
Everyone has a great time, except for Sayuki, who assumed Koharu would be bad a bowling (she isn’t). Koharu beats everyone, and gets to command Shouma to call her by her given name. Later, with Keiki, Koharu declares their contract complete (she deleted his photo long ago, knowing he’d keep his promise). What’s left to do, only she can do: tell Shouma the truth about her age, and confess her love.
Keiki cheers Koharu on, but as he knows Shouma so well, also has a pretty good idea how it will go. And so it goes: as soon as Koharu shows him that blue ribbon indicating she’s older, he dumps her on the spot, citing his lolicon as a disqualifying factor in dating her. Koharu runs off crying her eyes out, heartbroken.
Later, with Keiki, Shouma admits dumping Koharu broke his heart too, and was one of the hardest things he’d ever had to do. Keiki understands that Shouma can date whoever he likes for whatever reason, but still thinks it’s bullshit for him to give such a lame reason for utterly crushing Koharu’s dreams, after she spent a year mustering the courage to even speak to him.
As Koharu is about to start deleting her pics of her and Shouma, Keiki comes in to cheer her up, telling her only Shouma is at fault here for being such a rotten guy beneath his good looks. The Two Minutes Hate is interrupted by a contrite Shouma, who suggests a compromise: between getting over his lolicon and dating her, he needs a “rehab” period.
Koharu hits back at him by saying he’s essentially asking for his cake (not “Keiki”) and eating it too; he doesn’t want to be exclusive, but also isn’t willing to cut her loose for good. In other words, he’s the worst! Koharu dials it back, saying she’s just getting back at him for dumping her so harshly.
But then, Shouma wonders why it’s so dark in the club room and turns on the lights, revealing the hundreds of candid photos of him Koharu has collected since falling for him. With that, Shouma has a very good reason for not wanting to date her…such obsessive affection would quickly turn to hate if things ever went south.
Still, I wonder if, like Keiki with all his admirers, Shouma will make good on staying friends with her. She could help him get over his lolicon, and he could help her…stop so aggressively stalking him? ¯\_(ツ)_/¯
