Nope, for some reason they never get pregnant till it's relevant LOL. But this story Miyuki never gets pregnant (Neither does a certain other "plaything" of Kondo who he had LONGER then Miyuki, or another sex partner he had as long as Plaything #1! Seriously is the fuckboi "Impotent" unless the plot says so LOL)
Though what you said DOES bite her in the ass later, the IMPLUSIVENESS I mean, and not by HER, more by Kondo himself
After a disastrous game against another team and Kondo getting reality that he isn't so GRAND a soccer player as he thought from his ELDERS as the team are older and their coach also chimes in, giving him ADVICE he of course isn't going to listen to because "NARCS DESPISE WHEN THEIR TOLD THEIR NOT ANYTHING BUT #!" He takes Miyuki out on the Town as usual, and that moment pulls the "I can be BETTER then Eiji could ever be as your Official BF" likely to get Miyuki MORE under his dumb and the idiot almost considers it as it becomes more and more clear she and Eiji are FINISHED. By the way she wasn't suppose to be OUT at this time and she's been LYING to her mother about still being with Eiji as a COVER, bitch is taking advantage of her mother's TRUST to get away with whatever she wanted because she is a CHILD mentally, as in she sees something she wants, and KNOWS she's been a "good girl" that she lies to her trusting parents because she doesn't want to hear NO despite knowing if they get found out, that's IT for trust! Though like with Eiji when she first CHEATED she thought she could SALAVAGE the situation
But at that moment as they were walking to a Love Hotel, was when they get stopped by Officers who got a Tip off about Minor's about to "do something they shouldn't" as even if Laws about sex is "loose" in japan on the subject. There not THAT loose. Both PANICK, Miyuki terrified she will get caught and exposed to her mother, and Kondo finally shows "his true alpha self"......by PUSHING the officer instead of keeping it cool and lying and telling Miyuki to "run for it" while abandoning her to save himself! This gets his ass TACKLED and arrested of course as well as EXPOSING that they WERE going to do what the "Tip" claimed they were going to do, Miyuki is taken as well to the Station
I so LOVED when Ms. Amada came in, Miyuki's first move was to "Try and lie and say she was out with Eiji" before she got the SLAP she so rightfully deserved. Idiot forgot "MS. AONO AND HER MOTHER ARE CLOSE FRIENDS! MEANING SHE WAS BOUND TO HAVE FOUND OUT THE TRUTH FROM MS.AONO!" Meaning like with the Interview this chapter, Miyuki once again "missed her chance to confess the truth and even at this point chose to LIE! So she gets the FOURTH DEGREE and "what has she done" and when Kondo not minding his business tries to "interject" like he's the "new BF" Ms. Amada takes ONE LOOK at the Boy who "tempted her daughter away from Eiji" and has a LOOK of horror at how SIMILAR he is to Miyuki's Father! The Man who ABADONED HER AND MIYUKI THAT WITHOUT THE HELP AND SUPPORT OF THE AONO'S! MIYUKI WOULDN'T HAVE HAD HER GRAND CHILDHOOD OR LIFE THAT SHE IMPLODED LIKE AN IDIOT! That had to SMART as lets just say she's not in the BEST of health because she had to work WAY HARDER THEN SHE SHOULD HAVE trying to make a "good life for Miyuki" and well.. you can see why she gets PITY and WHY Miyuki is even more HATED by the Novel readers BEYOND just what she did and continues to allow happening to Eiji
So its seem like once the girls received kondo's jizz they straight off become stupid af, like drooling type stupid. Moron hormon def stacked up to the max up there. 10 years just goes poof!
