Hello! I hope your having a nice day. I was thinking abt this and I thought that you could give me some insight. What do you think Yuki's and Shizu's relationship was like? We know that him and Hiragi got along very well. As Hiragi admired him. But it seems to me that in that chapter (I don't remember the # sorry!) Were Mafuyu asks Shizu advice for music and his relationship abt Ritsuka. That when Shizu gets WAY of topic and says that the group was super Yuki-centered and how that was irritating. It seems to me that maybe he didn't like how much everyone revolved around him and admired him? As if it irritates him? Idk we don't really have much insight from him what his relationship with Yuki was like. So we might not be ae to tell for sure.
Hello friend! Thank you! Hope you are having a good one too! I'd like to point you towards this meta of mine, Discovering the true intention behind Shizu’s actions in Mix_8 completely changed how I saw the Shizuragi ship! This meta, although it doesn't address your question directly, I think it clears a lot of things up so PLEASE READ before proceeding.
Shizu and Yuki's relationship explained
In my opinion, Kizu never fully goes into the details of the dynamics between Shizu and Yuki but out of everyone, Shizu felt least close to Yuki compared to Mafuyu and Hiiragi. Shizu feels like
Yuki adopted the abandoned Pomeranian and calico cat and he's just tagging along. But Shizu feels like he doesn't belong to the squad/isn't as close to Yuki is his own doing due to:
his own abandonment issues resultant from being a LITERAL foster child
him joining the childhood squad later than the rest of the three
thinking that his three friends as being better than him from birth.
In mix_9, Kizu's placement of Yuki, Mafuyu and Hiiragi on stage is literally so telling of how Shizu felt. Of course he could choose to be on that stage as well, but he needs help to make he feel like he is worthy of being on stage.
Hiiragi is amazing, because Hiiragi noticed that Shizu needed help, Hiiragi had always been leading Shizu ever since he was a little kid. Hiiragi is absolutely that kid who is annoying but makes everyone feel included. And Shizu, is so happy and appreciative of that
to the point of feeling possessive over Hiiragi.
Sometimes, people with abandonment wounds feel possessive and jealous easily. This is because they are always scared that everything good can disappear at any moment. It may result in a person feeling super clingy emotionally. In Shizu's case, he is outwardly nonchalant but inwardly super clingy. Shizu, at some point in his childhood started to romantically idolise Hiiragi.
SO, Shizu's felt irritated towards Yuki because Hiiragi idolised Yuki.
BUT, Shizu's own abandonment wounds clouded his judgement because he mistook Hiiragi's idolisation of Yuki as a romantic one instead of a paternal one. Shizu mistook Hiiragi as being in love with Yuki when Hiiragi actually put Yuki on a pedestal like a child admiring a fatherly figure.
Yuki I think for the most part didn't do anything objectively irritating to make Shizu dislike him. Neither did the squad, they were always hanging out together. Shizu's inferiority complex and attachment towards Hiiragi made him look for someone contrasting his own circumstances to blame, which was Yuki.
Yuki - most panels depict him as the popular kid
Shizu - the literal foster child
Yuki - has both Mafuyu and Hiiragi's attention
Shizu - feels like he has none, but in truth Hiiragi is quite observant of Shizu's hesitation in participating fun things to make an effort to include him.
It's basically like the song Heather by Conan Gray.
Because Shizu also saw Yuki as being better than him in the literal sense, this actually didn't allow Shizu to really understand Yuki as a multi-faceted person. I think Shizu for the most part just accepted Yuki as someone with better circumstances than him, even beyond death. BUT AGAIN, that doesn't make Shizu a bad person. It makes him a human one. On top of that, Shizu's abandonment wounds were exacerbated when Hiiragi continued to emotionally dump on him whenever he wanted to but look towards Yuki for motivation and inspiration. And those are pretty VALID feelings which needed to be communicated and addressed for healthy healing, which they were in mix_4 to Mafuyu and mix_8 to Hiiragi. As you pointed out, Shizu gets off topic with Mafuyu, this is a great thing because for once, he is acknowledging his own feelings outwardly rather than keeping them inside. This then led him to realise that he needed to clarify things with Hiiragi rather than let these feelings of abandonment brew longer.
Currently, I personally think he is no longer irritated at Yuki. Please remember that Shizu also lost Yuki. Grief for him could have also manifested as irritation. It’s all very complicated when you lose someone right? I think Shizu’s probably found the new song “To the Sea” just as healing as Hiiragi and Mafuyu, he’s just not really the outwardly expressive type. But Kizu Natsuki did put in some tender faces in the recent chapters.
Again, please read Discovering the true intention behind Shizu’s actions in Mix_8 completely changed how I saw the Shizuragi ship! (sorry for pasting again, it's just so important, I go into Shizu's insight so much more here).
As for Yuki, we never really get to have an insight into how Yuki feels about anyone, because he's passed away. We are only ever receiving second hand accounts of Yuki. But Kizu wrote it that way to highlight the fact that life is precious and if you're alive,
there is hope for you to tell your story and communicate clearly.
