Spoiler warning:
i dont think gusam killed anyone. Im pretty sure its heavily implied that K, the blonde delinquent kid did it. I believe gusam when he says he cant remember he might got drugged ngl i was skipping too but anyway, like gusam pointed out he couldnt cut up the rapist so how was he the murderer that time it just dont make sense. Im also disappointed that the first murder wasnt cleared up but ehh i guess its fine

people may see the ending bittersweet but i'm glad they got reincarnated and met again, i'm not too sure if the grandma was also reincarnated (since somebody said they saw a familiar face) but i hope so. the last 2 chapters made me cry so much because of what they had to go through just to live properly. though i won't lie and i will ask this, the murder case is so vague, like there were not too much detail or i must've skipped over. who did gusam kill? and was the date being on the start of the olympics coincidental?? please enlighten me thank you!
