Madarame Hiro loves these twisted love stories. They aren’t supposed to be healthy, normal relationships, but maddening, obsessive and irrational. The ‘uke’ needed to feel unconditionally loved and pushed the limits of that love to see how unconditional it actually was. When that started to disappear because the ‘seme’ wanted to be loved too, the ‘uke’ realized how much he actually needed and loved the ‘seme.’ And ultimately the ‘seme’ loves the’uke’ and seeing jealousy and love from the ‘uke’ was all he needed to bring him back. Hopefully, now they can have a real relationship, but it will always be twisted, because that’s how these characters are written. (Uke and seme are in quotes because we don’t ever see or hear who is which. We can just assume.)
I agree with u that Kou's persona is shit. But whether he's the nicest person in the world or not, saying to hell with cheating is quite insensitive...It doesn't condone the act of cheating.
And like srsly C'MON it's Madarame Hiro sensei's work we're talkin bout here this kind of unstable relationship is to be expected.
Plus if we're gon' criticize Kou's egoistic behaviours then I would like to point out Ichii's infidelity despite claiming selfless love towards Kou and Megane guy's selfish desire of wanting to be desired despite knowing the guy had a boyfriend! They're all twisted in their own ways and no one is better than the other so Seeing ppl critizing the uke for being like this or that is quite irritating.
Yes, it's true that Kou's foolishness that Ichii's gon' love him unconditionally is what forced Ichii to take that step and yes it's also true that Ichii is only human and wishes to be loved as much as he gives, BUT CHEATING IS JUST NOT RIGHT IN MY BOOK SORRY!!!
Plus look at the bright side of this!
Kou will reflect on his actions and try to improve himself! Ichii's love is finally reciprocal and megane guy will just have to find happiness elsewhere while them ppl still be twisted as f***

i hate the personality the uke has. there are a lot of mangas where the seme is manipulative but the reason is to lure in the uke. to make the uke realize the love he has for the seme but this manga's uke is different. he manipulates the seme by being superior to him just because he knows that the seme likes him. and doing that since middle school or high school? why the hell would you treat your partner like that? he treats the seme like a dog who can only obey and listen to his verbal abuse. cheating? the hell with it. the megane seems to be a nice guy so why wont he choose him? btw, with the way the uke is i bet the seme thought that he doesnt even care if they break up. the seme even looks surprised in the end because the uke cried. being together for that long and thats the only time he showed any affection?! wtf is that. ヽ(`Д´)ノ such bad personality. makes me sad.
