I skimmed through the novel again at the urging of someone else and found a part they told me where Ritsu (the loud mouth female friend of Miyuki) had been talking ALOT OF SHIT prior to all this shit show about how Eiji wasn't worthy of her because she knows little to nothing about him and knowing her connection to the jocks of the Soccer Club, she seemed the type who designated Eiji a "average unexciting nerd" and that Miyuki can do better (Never trying to understand Miyuki or her tastes, she just assumes she just hasn't experienced other males out there and is "settling too soon" with a Childhood friend just cause! Happy to know that behavior and poking comes back to BITE HER IN THE ASS as she never thought the Soccer Club would COVER Kondo's shitty behavior THEY KNEW ABOUT from her! Hence why she never saw him as the scum he was, a playboy like sure, but like Miyuki.....and Eri, they make the mistake of falling for that "Jerk with a Heart of Gold" cliche and learn the hard way that....no he's just a "Jerk with a Heart of Jerk" and a POS!) and the worse thing on it, Miyuki NEVER stuck up for Eiji EVER in these cases!
Miyuki in truth was scared of others stealing him from her, this is the major reason she hates Ai, because she became that EXACT FIGURE SHE FEARED WOULD SHOW UP ONE DAY! But the kicker is, Ai never stole him! For all her fear of him being stolen away, SHE HERSELF NEVER FACTORED BEING STOLEN HERSELF FROM HIM even though I don't see cheaters as STOLEN but more "running away and thinking it's temporary or whatever they see it as, after all, if THEY say it isn't cheating, then it must be true despite what their doing is by all definition CHEATING!!!!" And SHE was the one to say they were "broken up" her own LIE to justify "she didn't cheat" all while "still lying to her mother that they are still together" shows she was too immature for a relationship PERIOD! She never ever considered that Kondo saw her as a one-night stand and nothing more! Letting her THINK she was IMPORTANT was the goal to keeping her a Fuck Buddy! Just ask Eri (His victim from the flashback, speaking of her, her role in the story isn't over, she WILL return as turns out, remember when I said he sees Miyuki as a FUCK BUDDY and only gives her the DELUSION she's his girlfriend as he KNOWS she'll jet the second she realizes her delusions were WRONG! Yeah Eri is STILL WITH HIM! After the humiliation she went through and STRUGGLING to get into High School, narrative was CRUEL adding that Kondo got in no problem just to show he lost NO SLEEP in what he did to her or any girl he fucks with in general! She ran into her childhood friend, the nerdy glasses kid she cruelly ended their relationship with because Kondo told her to as he was corrupting her! She actually thought he would "take her back" after what she did those years back, worse in that she never apologized and like Miyuki, just ASSUMED because people like them take for granted the KIND PEOPLE around them, it becomes noticeable once someone like Kondo brings it out as Miyuki showed throughout! "Eiji is kind, he'll forgive me no matter what" like what she did was FORGIVABLE! That is what makes a HORRID CHEATER, the assumption that KIND PEOPLE have to forgive or "their not kind people" like THAT has any weight what so ever and just signel's they see Doormats they can walk all over! See Eri, like Miyuki currently hadn't learned her lesson. And well, before she could even TALK to her "EX" the Boy just GLARED SUCH HATE AT HER (Something she NEVER EXPECTED FROM HIM because again "he was always socially akward and a kind boy) that in fear of being set on fire or something, she wisely fucked off without any talking! This caused her to run back to Kondo and beg him to take her back, and Kondo made her OFFICIALLY his Fuck buddy (she has to EARN his full attention......AKA She became a convienant woman he could exploit for sex and later free housing as her parents were so DONE with her, they gave her an apartment just to not LOOK AT HER anymore, she ruined her life THAT BADLY especially as it's made clear once she reaches adulthood, they will stop providing and she'll be disowned.....As said Eri and Miyuki have ALOT in common beyond being victimized by Kondo, they had BRIGHT FUTURES they destroyed for him and he doesn't give a shit as expected) she actually goes to ALL his games cheerleading for him in the audience while just being seen as an Ex-Stalker that follows him around by others by his own WORDING!
He has her number in his phone, knowing HIS "classy ass" she's titled "Plaything Number 1" (Take a LUCKY Guess who is Plaything Number 2 on his phone) and well lets just say Kondo made himself a DANGEROUS Enemy, NOT when he fucked with Eri, that was the ground work to it. It was when he TARGETED "EIJI AONO"
That Nerdy Kid I mentioned, his name is Endou and that nerd rage he had for those two was actually nearly calmed down because he met Eiji one day and Eiji being Eiji was able to help him finally get over the two and take his life back, guiding him to what he actually loved, with was "photography" (this becomes relevant to the story LOL) he was ready to HAPPILY forget Kondo and Eri's existances.....till Kondo targeted Eiji! To Endou, Eiji is a good kid and Kouhai who DIDN'T DESERVE what was being done to him, "what happened to him!" so this is the straw that made Endou decided Kondo needed to be DESTROYED! Kondo never learned to not make enemies cause he assumed he was untouchable! And Endou shows JUST HOW EASILY someone like him can be destroyed! The story as shown in this chapter shows Kondo, Miyuki and the MASTERMIND in the end are just teenagers who don't fully UNDERSTAND the world yet. IT's why they have a sense of thinking their the smartest thing in the room! When they are not! Kondo could have acted humble and less smug, but by not keeping his ego under control, he made SURE the teacher KNEW he was behind everything, this means the man is just going to keep looking till he finds evidence and YES THERE IS MAJOR EVIDENCE out there that WILL make these interviews come back to BITE the Soccer Club, Miyuki AND Kondo later. BELIEVE ME ON THAT
But basically Endou starts stalking Kondo, taking pictures and the best part, when he and miyuki go to do their USUAL Fucking, he calls it in, and the cops get the two RIGHT as they left the Hotel (and Kondo makes you hate him MORE by asking Miyuki to dump Eiji completely and date him, that he'll be LEAGUES BETTER and Miyuki ALMOST considers it before the cops come! Kondo's act falls apart as remember when the teacher mentioned he's not good at poker face like he thinks! Realizing he can't talk his way out of the cops taking them to the station....dumbass ABANDONS MIYUKI and tries to run for it, FAILING and Miyuki is in PANIC cause she KNOWS her mother will be called and at this point "she is still lying to her mother that she is with Eiji!" and well she stupidly assumed Ms. Aono, HER MOTHER'S CLOSE FRIEND wouldn't tell her which she did RIGHT AROUND when Miyuki "snuck out to do this shit" meaning she had MORE THEN ENOUGH TIME TO CONFESS but like with the Interview with the Teacher, Miyuki is a coward and scumbag so she didn't! So it is SO STATISFING when she tries to lie and throw Eiji under the BUS for the Pick Up and Ms. Amada FUCKING SLAPS HER and calls her out! At that point Miyuki has lost the ONLY FAMILY SHE HAD LEFT Trust! Hence as you said, It's not about how she LOST Eiji, the PERFECT BOYFRIEND, She lost the TRUST others had in her, she WAS willing to do stupid things AND lie to everyone who loves and trusts her about it thinking she can get away with it! But lets just say this will be the LAST TIME Miyuki has SEX in the story, I fanthom she will be a NUN by the time this is all over as "Wanting to know what sex was like and cheating will be PTSD for her going forward" She destroyed her "Perfect Girl Next Door Honor Student" reputation, and well, I'll get to the "for Nothing" in a bit!
Endou scares the Soccer Club into thinking one of them has become a SNITCH, destroying their unity and making them unavailable for Kondo to use as his minions before they are EXPOSED for the bullying they helped do to Eiji and are DISBANDED and the members EXPELLED! The Captain of the team who was interview is the WORSE, he was SO FOCUSED on his University Prospects that he KNEW Kondo was using the Club for his own purposes, but instead of DEALING with that, he abandoned his juniors to focus on himself! Even LYING about not knowing what was going on to play ignorant. While he did nothing the club members did, he still knew and lied, so he can FORGET about his Prospects! Doing nothing in this case is the same as HELPING as the LEAST he could have done is TELL THE COACH who gets a pass cause the club hid and helped Kondo cover up the shitty things he's done! And the man like the rest of the staff is HORRIFIED at what his boys have been DOING, especially Kondo who'd he'd have thrown out the club if he knew he was THIS MUCH OF A PROBLEM CASE! But without them turns out Kondo is NOTHING as he has no patsy's anymore
And Endou removes his FINAL CARD! His playthings! Endou can care LESS about the two, in his eyes Eri is WORSE for still hanging around Kondo after what he did to her, though he has a moment of hesitation, showing she wasn't wrong that their FRIENDSHIP wasn't gone from his heart, she was only wrong in that HE was the one to treasure it, I think she later felt GUILT for what she did and not in the "regret because she couldn't rely on him, but more GUILT at the person she let Kondo turn her into that even her PRE-Kondo wouldn't recognize herW! A ONCE Smart Girl who had loving friends and a childhood friend she was close to, now a loser who thought with her groin and was akin to an abuse victim who STAYED with a constant cheater she KNOWS is horrible, yet still HOPES he'll go back to the person he was when they first got together.....despite knowing even THAT PERSON WAS FAKE but trying to deny it, because admitting it would be admitting she wasted her life and future for NOTHING. Same like Miyuki who Endou sees as Eri 2.0, hating her even MORE then Eri and Kondo as she was the one to HURT EIJI THE MOST! Kondo could ONLY do what he did BECAUSE OF HER! The reason I say this is he was stalking their "dates" with Kondo, and took VERY GOOD PICTURES of them, which was when they were wearing GIFTS that Kondo gave them......Gifts the OTHER GAVE HIM THAT IS! Kondo despite being rich enough, isn't going to waste too much on idiot "ASSES" who exist just to be fucked by him! But the Gifts themselves MEANT SOMETHING TO THE GIRLS
To Eri, Miyuki was wearing a Gift that she gave Kondo "the day she betrayed Endou and all her previous beliefs for him" and that one hurts her HORRIBLY because it finally wakes her up that the shitbag never loved or cared for her at all! She was ALWAYS A JOKE, even as she BEGGED after sex to not cheat on her, even AS she knew he still went for other girls, it was the showing he never cared since DAY 1 that wakes her up! The worse thing is Kondo didn't target her on a whim EITHER! Tachibana and he MET around that time, that was their first meeting together and Eri was a Top Grade Student, Tachibana showing that HATRED of anyone better then her, sic Kondo on her. Kondo dumping her was because he got bored and completed the task Tachi gave him. Eri was so far from the girl she was that she'd NEVER be able to be a Top Grade Student AGAIN! He just keeps her around for his amusement and advantage. And that is pretty sad as she was almost going to kill herself before she decided NO she won't till she's made amends AND MADE KONDO PAY FOR PLAYING WITH HER!
To Miyuki, It's Eri wearing HER GIFT that was meant to CELEBRATE their relationship! Yes she got him a gift that symbolized HER CHEATING ON EIJI though reminder in her mind at the time, "it wasn't cheating" but IT'S THIS which FINALLY causes Kondo to lose control over Miyuki and is the beginning of the end for her! She gets the pic RIGHT AS Kondo calls her for help, and when confronted during the call, he decides (After failing to convince her it was a PAST FLING as the Jewelry gift from her exposes that as a lie on the spot) to cut his losess and get that DESPAIR he wanted from her right then despite NEEDING Miyuki's help at the moment (idiot can't help himself and still thinks he has control! Even as he's landing in Juvie, the fool is STILL SCREAMING about his Soccer Dream! Even as his family's EX LAWYER has to spell it out for him that ain't ever happening in this life!), calling her clingy and a FOOL for thinking he'd EVER just have one girl friend, or that one would be HER, and having the NERVE to be upset she was cheated on, when she was cheating on Eiji with him! So much for CARING ABOUT HIM. She was such an EASY SLUT! That breaks her as she finally FINALLY realizes the mistake she made in EVER GETTING INVOLVED WITH HIM. This will bite him in the ass later cause as I said, Miyuki is FINALLY FREED from his spell....it only took him being horrible to HER for it to happen! And she STILL doesn't confess till the second interview with the teacher as at that point she's been caught and it's OVER! And at least she admit the truth when asked WHY! She was trying to save HERSELF! She tried to convince herself otherwise, but she knew the truth, she was a selfish bitch, trying to save Kondo was an excuse to cover that the only one she was thinking of was NUMBER 1!
