He didn't want to kill hinata, evenwhen he still in highschool he gave up on the painting because imhe need to kill hinata to finish it. Also the pedo is the one stabbed hinata and that's the reason sora realize he didn't want hinata to die. But after the time skip, he know he killed 4 people and he'll be in death row jail or something so he can't even meet hinata anymore so the only way for them to be together is they both die
Braw, hinata literally go back to when they were kids because after sora tell the story he drowned hinata. Also sora didn't really kill the teacher the creepy peds teacher use sora's hand and stab himself because sora didn't want to continue.
When hinata go back being a child he finally noticed how sad sora is and confront him in the park little sora finally open up to hinata and ask for hinata's help, buttt shitty mom hears it and didn't know exactly what she does to sora (hopefully not kill him) but when hinata go back to sora's house she just said that sora is in hospital for heart problem i think. And she said something about the park which ofc letting hinata know that she knows what happend. Also in the last part hinata said "that person can help", dunno who tho
