im not sure if someone posted this but im pretty sure if you save the scene and keep re-loading (reload save of the scene idrk how to word im- SORRY! T_T) the three days go way quicker and you basically 'skip' through it (the three days being Yuri's death- aka her body decomposing after the Yuri event). if this doesnt help, just search 'Yuri death scene ddlc' or 'how long does Yuris death go for/last (/scene/event) and go onto the reddit post. It helped me, and i sorta tried explaining here. Ill see if i can link the post im referring to.
(I kind of worded this wrong and confusing i really apologize. The top comment on the post im linking explains it way easier! Hope this helps!) (https://www.reddit.com/r/DDLC/comments/otrcvc/yuris_death_scene_no_skips/)
