I think people greatly underestimate how much love there is in Tsukasa Yugi. Yes, yes, weird autistic evil sadistic twink, antagonist, etc., "problematic dude", so much so that many people do not accept any pairings with him at all. And this is fundamentally wrong! The boy had so much love for his brother that he died for him, so much self-awareness that he doesn't get jealous of Nene as much as he could. (He could really just hate her because Amane loves her and him doesn't. But he continues to treat her like a friend and a big sister. You can consider his behavior in the tea party and festival arc nasty, but hey, he obviously did all that in order to touch Amane and involve them both in his plan. When he doesn't want anything from them, does he intentionally torture them with sadistic pleasure? Something like the "theory that Tsukasa bullied Amane in life", which has been criticized more than once.)
I stepped aside... he could hate Nene or that same Kou, who is preventing him from working on Mitsuba, but he doesn't. Everything he says regarding his specific grievances are just half-statements - "you killed me, and you're protecting her?", "I shouldn't have done that to Mitsuba?". He could have been much angrier, especially at Amane, but he continues to forgive his brother who betrayed him, constantly hurting him, continues to babysit Nene and calls Kou into the world that was ordered for Amane and his goals with Shijima.
Well, speculation, lore moments can be refuted, but you just don't understand 🤌🏻 how much love there is in Tsukasa. He devoted his life to this, even after death he continues to fulfill other people's wishes, help others, everything to others, others, and what about himself? What did he ever demand for himself personally? His sense of healthy egoism died, frankly speaking, he constantly forgives others for their bad attitude towards him. And almost no one loves him. His parents abandoned him, his brother betrayed him and started ignoring him, Nene has almost no time to get closer to Tsukasa, everyone else considers him annoying at the very least and a monster at the most. Tsukasa always gave everything to others, sacrificed his well-being and desires, and in the end, he receives almost no emotional return. What could little Nene say? Amane decided that his brother was a fake after all. And no one else can give him anything. People are kind to Tsukasa once in a hundred years, lol. And he still continues to help them.
Tsukasa loves his betrayed, hated by everyone, pathetic at his core, brother very much. An interesting feature - he loves not for something good, not for something, but just like that. Like Nene fell in love with Amane, like Sumire fell in love with Hakubo, cringe from the outside, and they love them - because it is their pure feelings. And for Tsukasa, I think, there is no concept like choose from your favorite people or who you love more. It is clear that he is fixated on Amane, but even so, I do not think that he would leave the same Nene in danger, "choosing" Amane. Tsukasa is about caring too much, so he would definitely try to somehow solve the problem so that he does not have to "choose". And so that others do not have to choose. An interesting parallel with Amane, who can say that he likes Yashiro more than Aoi-chan, so that's it. The joke is that Tsukasa is so strong that he rarely has to choose and this is a straight Leorio reference or something like that. That's it, he is a gigachad, there are no boundaries in front of him, which means you can just help everyone, generosity from wealth. Kou doesn't have this and you can understand him in your own way...
I care about little Tsu inside his usual appearance 🤲🏻 the trauma especially clearly makes it clear where the roots come from - from that child's motives. Everything comes from that child's motives.
Pairings with Tsukasa are about "finally he has someone to give his care to, finally there is someone who cares about him, someone who will give him the love he hasn't received since he was four", and not about "well, he probably likes to beat and torture his partner, because he is so chaotic in canon, so he is a sadist and he is terrible in relationships". In relationships, he is so self-sacrificing that it is to his detriment, while he will literally do everything in his power for the happiness and well-being of his beloved. To not see this in Tsukasa, you have to intentionally not look at him, because it's on the surface... right after "we'll introduce him to the readers as the evil Hanako for the sake of plot intrigue". He's not the evil Hanako, you see. The whole parallel between the brothers comes down to how good they both are at giving their love to others, and Amane does a lot worse than Tsukasa in that context - that's his character, a reversal of the reader's opinion, the evil Hanako is Hanako herself, Tsukasa isn't "a worse version of him", he's just another version of him. Completely misunderstood by everyone - the superficial, picky fandom, the outside characters, his own brother. Oh, Tsukasa definitely deserves love, as much as he gave and more.
