LIL EXPLANATION OF THE MIRROR STUFF FROM A HORROR FAN

There are malicious entities into all the mirrors of the world and they exist as an alternative reality which can be summoned only under certain conditions: the person summoning these entities must be in a black room during a thunderstorm and if this person wishes for something there, the entities of the “mirror world” will make it happen. But their main goal is (of course) to kill, since they’re the reflection of the cruel part of the human nature, so they accomplish people’s cruel desires by swallowing into their world the victims whose limbs become new means to drag by future victims inside. These entities also seem to be highly manipulative, which explains the gradual yet radical change in Yeonwoo’s personality from scaredy-cat to killer. We aren’t able to define for sure whether the guy in the cinema and the man in the streets were killed because of Yeonwoo’s wishes (perhaps to force Jun to remember as soon as possible?), however we can affirm that Jun’s hallucinations were not just hallucinations, but a way Yeonwoo used during the years to keep his eyes on him. This explains why Jun thanked Yeonwoo for taking care of him and why Yeonwoo seemed to know before Jun himself what he liked (about sex and other stuff).

I hope this lil explanation has been useful to everyone who’s been left confused by the “rushed” yet intriguing (almost) open ending~.
