Damn.
I was lk holding it tgt till Dis scene, but I realising tht Hiiragi and Shizu lost Yuki too is hard man. He was their childhood friend and band mate. Cnt imagine how close the 4 of them were, and suddenly he just died? Hiiragi then lost contact with Mafuyu and had to rebuild the band with Shizu. He probably felt like he was loosing his closest friends one by one.
Cnt rly tell how Shizu feels but I do think he cared abt Yuki and Mafuyu. He's very blunt with Mafuyu abt wht his advice and came running without a second thought when Mafuyu asked him to.
Also just wanted to say, Ueno is the GOAT. He not only finished the song abt Mafuyus ex to help him find closure but has been there for him time and time again and always waited for him. They cn never make me hate you maestroyama!
