Rin Ito and Ai Hayasaka continued their date, while Kaguya returned to Kaede and Chika, reverting to her usual cold demeanor. After helping Kaguya put on her trench coat and deerstalker cap, Chika looked at Kaguya with confusion.
"Is that it?"
Chika and Kaede were both expecting a dramatic fight over the man, but Kaguya just came back after running away in tears? That's it? That's all?
Kaguya lowered her face, feigning the look of utter defeat after having given her all. "Yes, I realized I'm no match for Ai Hayasaka."
"Huh? Huh? Huh??? Shinomiya-san, you haven't even tried, so how can you say you're no match?" Chika puffed out her cheeks, angrily cheering Kaguya on. "You can't give up so easily! Don't you want to reconcile with Ai Hayasaka and see him realize he's being fooled by her?"
"No way. Ai Hayasaka's chest is bigger than mine. Men are chest people; a small bust can't defeat a large bust."
"...."
"...." Kaguya knew Ai Hayasaka was padding and that their actual sizes were similar. The talk about a small bust not defeating a large bust was all nonsense. But... should she reconcile with Ai Hayasaka by offering herself to him? Kaguya had indeed planned to do that initially, but when Chika arrived, she had a flash of insight for an alternate plan... Chika Fujiwara, the "Cancer of the Earth," had such a large chest; wouldn't it be a waste not to use it?
"Fujiwara-san, can you use your vulgar chest to steal him away from Ai Hayasaka for me?"
"Huh? Huh? Huh? Huh? Huh!?????" Chika's expression instantly became flustered. "Shinomiya-san, didn't you say you wanted to make Ai Hayasaka experience betrayal yourself? If I do it, that won't be right! Besides... Kaede's chest is also large, and she likes him! Let Kaede do it!"
Tch... Big-chested, and smart too. Kaguya clicked her tongue slightly, but she had already prepared a countermeasure.
"The dating part is for me, but when he needs to vent his beastly urges, Fujiwara-san, you use your vulgar chest to tempt him and let him vent on your cleavage."
"What is 'venting beastly urges'!!!!" Chika's face was crimson. "Kaede also has a large chest and likes him, so why can't she do it?"
"Because she's already a losing dog," Kaguya said flatly.
"If that's the case, then it proves a large chest doesn't work on him, so Shinomiya-san should just do it herself!!!" Good heavens, Kaede exclaimed silently. When did Chika get so smart? She managed to circle the argument right back to Kaguya!
Tsk... Kaguya pouted, then launched into a seamless sequence of moral manipulation. "Fujiwara-san, are you going to stand by and watch the man who saved your friend be deceived by Ai Hayasaka? Only you can save him now, Fujiwara-san. If you don't help, he might even commit suicide after being abandoned by Ai Hayasaka." For Kaguya, who was raised on a diet of self-interest, using Chika didn't cause any psychological distress. For Kaguya, everyone was a tool, except for Ai Hayasaka and Nao. Moral manipulation was a basic technique, to say the least.
"Ehh..." Chika looked troubled, glancing back and forth between Kaguya and Kaede. She only wanted to watch the fun... how did she end up becoming the fun herself!?
Watching Kaguya manipulate Chika, Kaede raised an eyebrow, a flash of insight striking her. Then, she discreetly winked at Chika.
Although Chika really wanted to refuse, being watched by both Kaguya and Kaede made it impossible for her to say no. And... Kaede seemed to be winking at her? What did that... mean?
"I... I... I'll try my best. Don't blame me if it doesn't work!"
Seeing Chika agree, a hint of pleasure appeared on Kaguya's cold face. "Of course. If you try your best, Fujiwara-san, I won't blame you even if you fail."
Meanwhile, Rin Ito, listening to the synchronized audio from his System daughter through his earphones, almost burst out laughing...
"What's wrong, Ito-kun?"
"Nothing." Rin Ito glanced at Ai Hayasaka next to him, who was playing the kouhai clinging to his arm... What brilliant idea did she come up with now?
Rin Ito and Ai Hayasaka spent the entire day together, but after dinner, they didn't go to a hotel for the final step; instead, they both went home. Besides Rin Ito's temporary lack of intention to eat Ai Hayasaka, there was another reason... Chika Fujiwara was waiting for him at home. More accurately, Kaede found a reason to have Chika temporarily stay at her place.
After saying goodbye to Kaguya during the day, they didn't all go their separate ways. Kaede, keeping it a secret from Kaguya, invited Chika to her house, and at the same time, she told Chika some things she hadn't known before.
When Rin Ito returned, Chika was playing a board game with Kaede, Suzu, and Nanami.
"Huh... Ito-kun!?" When Chika saw Rin Ito, the cards in her hand dropped. After instinctively saying Rin Ito's name, Chika realized that to keep Kaguya's secret, she shouldn't have met Rin Ito yet, so she quickly corrected herself. "Um... Kaede-san introduced her childhood friend to me earlier. You must be Ito-kun, right?"
"That's right, and you're Fujiwara-san, right? Kaede mentioned you to me before."
Just as Chika was bewildered, Kaede cleared her throat. "Fujiwara-san, let me formally introduce him. His name is Rin Ito, and he is... my boyfriend."
"Huh? Huh? Huh? Huh? Huh!?????" Chika's mind instantly froze.
Earlier at Kaguya's house, Kaede and Kaguya told her that he liked Ai Hayasaka and was being used by her as a tool, and Kaede was the losing dog childhood friend... Why did Kaede suddenly become his girlfriend now?
"Did you both lie to Shinomiya-san?"
"I'm sorry, Fujiwara-san, I know you're stressed, but please don't be. We've been lying to you all along... Here's how it is." Kaede spoke after a slight pause. "We've actually always been childhood sweethearts. The reason I pretended to be the losing dog was to help Shinomiya-san and Ai Hayasaka reconcile. He's actually only pretending to leverage his kindness to get Ai Hayasaka to date him."
"Ah?" Chika was completely confused by Kaede's explanation... What kind of layers of deceit were they playing?
"Stop, stop, stop, stop, stop... What exactly is going on!? Tell me everything from the beginning!" Chika placed her hands on her hips, looking angrily at Rin Ito and Kaede. Kaede then slowly started explaining to Chika.
It took a while for Chika to straighten out the situation.
From Kaguya's perspective—what Kaguya told her—Ai Hayasaka used Rin Ito to save her from the Shinomiya family. Kaguya wanted Ai Hayasaka to experience the feeling of being cheated on to retaliate against the one who betrayed her, and also to make her benefactor realize that Ai Hayasaka was only using him. Finally, she wanted him to end up with his childhood friend, Kaede. If Ai Hayasaka forgave Rin Ito's 'betrayal,' then she would reconcile with Ai Hayasaka.
But the actual situation was that Ai Hayasaka was so full of guilt about the betrayal that she didn't dare to reconcile with Kaguya. Meanwhile, Kaguya, though deep down she wanted to reconcile, was being stubborn and wanted to cheat on Ai Hayasaka first to make her forgive her before they reconciled.
Of course, Kaede didn't mention that she had polluted Kaguya's mind with cuckolding comics, which led to Kaguya's desire to cheat on Ai Hayasaka.
"I see... Simply put, you want to reconcile the two tsundere, Shinomiya-san and Ai Hayasaka. Yes, yes, I get it. How do you want me to help?"
Kaede glanced at Rin Ito, then looked at the massive bust on Chika.
"First... as Kaguya suggested, you need to use your huge chest to tempt him!"
"Ehhhhhhhhhhhhhhhhhhhhhhhhhhhh!?????"
