It seems something is missing, when he's able to see others' dreams in one of the last chapters ... it didn't continue
It didn’t show exactly what happened in everyone’s dreams, but when they discovered purple hyung’s suicide, it did show his dream in a flashback and in a way explained the reason why he killed himself, imo I don’t think at this point it’s important to see everyone’s dreams, but I agree, it seemed like following that point we would’ve been shown everyone’s dreams
...this story isn't going anywhere
That's the plot
